he made a class for non chem majors a class for chem majors. would get overly excited and would skip over important information that he assumed we just knew. he is very passionate about chemistry but terrible at teaching it. all exams are essay fill in the blanks and about 13 questions long and worth a lot of points.

Not very good at explaining things and does not offer adequate help when asked.

This has been the worst class I have ever taken in the history of my education. This class and lab is so poorly structured and so poorly taught it blows my min Chemistry could be so much easier, but the way Keller taught it was nearly impossible to understand. I don't have enough characters left but I would strongly recommend a different teacher.

He enjoys chemistry but doesn't realize how bad he is at teaching it. Odds are high that you can study for days in advance and do very poorly on tests. Just about every aspect of this class is unnecessarily hard. Lectures are confusing, be ready to teach yourself this class.

Keller is probably the worst teacher I have ever had

He genuinely wants us to fail. There are trick questions on the exam that we have never learned about in lecture or lab. We are not taught things on tests. This class has made me hate chemistry and I used to love it. This class and professor is overwhelmingly difficult. I do not recommend.

Don't do it to yourself. Regardless of how good at chemistry you may be, take Keller's class and you will regret it. He goes insanely fast in lectures and barely focuses on the important stuff. You get to the exam and there will be stuff you've never seen on it.

If I could say anything about Professor Keller, it's that he doesn't respond to emails, the class is the toughest thing I've ever done in my life, and this is the source of all of my anxiety :) take with ANY other professor if you can.

He's super passionate about chem but he talks in circles around the subjects he's teaching, and then tests on problems he never told us how to solve. I've never stressed so much over one class. Class averages are below 60 on exams. Lab is awful too. Be ready to put HOURS into homework and projects that arent worth much.

Absolutely the worst professor I have ever had. He is not accessible outside of class if your schedule doesn't work with his. While he is excited about chemistry, he talks in circles and doesn't get detailed about what you really need to know. He spent 15 mins showing an equation in class only to end it with "That is what I don't want you to do"��

worst class I've ever taken, 0/10 recommend! honestly worst professors I've had in history. i'm currently having to drop out of this class rn because its going to hurt my GPA badly. i've heard he is in trouble with miz too for failing too many students :) so don't take this course

The tests are extremely hard. The practice tests tell you nothing about what is going to be on the real exam. There is no curve. Aleks is a big help to your grade in the end so make sure to keep up with that. Labs are ridiculously hard. Overall this was the worst class and professor Ive had.

Keller's exams are nothing like the homework/practice exams. There is no textbook either so the only way to be prepared is to pay attention to every single thing that comes out of his mouth, which sucks because 75% of what he says is complete nonsense

Though Dr. Keller is very passionate about chemistry, he is not easy to learn from. He is accessible in office hours and willing to explain things. However, his tests are impossible and completely unpredictable. Lectures seem very basic and tests will cover things not even spoken on. FIND PRACTICE TESTS. Good luck.

100% the worst professor I have ever had! He does not respond to emails and he says he is open for office hours but when you go he does not answer your questions. The grading scale is confusing so I was never aware of my current grade! There is a ton of homework to do and it does not you learn the material, and there's no textbook! WORST CLASS EVER

For what is supposed to be a continuation of high school level Chemistry, this course was extremely hard. Class averages on exams were typically a in the 50-60% range, and the only curve was him setting the +/-. If you want to actually understand Chemistry and the concepts taught, take Ganley's course.

Dr. Keller is extremely nice and passionate about chemistry and his students. However, he is one of the worst teachers I have ever encountered. His teaching style is nonsensical and his tests are extremely difficult. Unless you understand chemistry on your own, don't take his class. I had to work extremely hard for a B.

He is a very smart and friendly man, but honestly has no idea how to teach a class. His notes and lecture are unorganized and just seem like a jumble of words. There will also be concepts on the tests that aren't covered in class or in homework which is rediculous.

As a freshman registering for classes, no one warned me about Keller and it was a big mistake. No textbook readings so I had to learn everything outside of class. Average on tests are around 50%, so watch out if you're looking to keep your gpa or grades up for scholarships. The tests are extremely difficult, with material not from class.

Grading scale is somewhat reasonable but not enough to balance the difficulty of tests. Tests involve things never discussed in class or even on the online homework. Ridiculous difficulty for being a first chemistry class to many. If avoidable, please do

Bruh I Thought I could handle this professor with a wicked bad reputation because I'm pretty smart. I was wrong. I struggled to get a C in this class and I spent 10 hours a week studying for this class. The exams are ridiculous and he does not do well to prepare you for them. He is a nice guy, however DO NOT TAKE THIS CLASS IF YOU NEED A GOOD GPA

I took 2 years of chemistry in high school and I still struggled in this class. Keller is a nice guy, but a terrible professor. His lectures are all over the place and his exams are even worse. He isn't specific about what he's testing on, or even what he expects you to learn. If you need CHEM 1320, find a different professor.

Way too passionate about chemistry so he doesn't explain things well at all, assuming everyone understands the concepts immediately. Tests are ridiculously hard and usually have failing averages. Has been on academic probation for failing too many students, so good luck!

Opted out of Chem 1320 as additional review although I did well in HS honors chem. Should have stayed in Ganley's 1320 instead of moving up to Kellers Chem 1000. He is nice but so advanced he doesn't know how to scale back and teach intro or basic. Tests didn't represent what had been taught. He wasn't any help in office hours. Out of touch.

Absolutely terrible. I graduated high school with a 4.0 gpa, literally got 99% in high school chemistry, and Im struggling so hard in his class. My roommate dropped out, my lab partner dropped out. The test average was a 62%. Thats failing. The majority of the class is straight failing. Whatever you do, do not be with Keller. Take any other prof.

he sucks

His class is insanely hard. Unless youre actually good at chemistry, you wont pass. Hes very strict, doesnt give any type of extra credit or grading on a curve. I learned better from his TAs than from the man himself.

Despite having a clear passion for the subject, Keller is not a good professor. Youll spend hours each week on the online homework that rarely correlates with what is taught in class. Lectures are incredibly quick, giving you little time to write down the material. Classes go over time frequently. He doesnt understand that you dont understand

Keller really loves chemistry and isn't a bad guy, he's just a horrible professor. He moves fast in class and talks a lot about things you will never see again, and skims over the important things. The class, lab, and homework may as well have been 3 different classes.

Labs, homework, and lectures did not correlate. tests were always curve balls and i could never anticipate what was going to be on there. lectures are general, tests are abstracts. homework was impossible to do on your own and took an extreme amount of time. hard grader with not a lot of explanation of how to do it. very test heavy.

The WORST science teacher I've EVER had. Lectures are very general and if you ask a question he will answer with sarcasm rather than actually answer the question. If you still dont understand something after he explained it again he will simply answer with "I've already answered that." and continue teaching. Absolutely horrible.

This guy has a hard time conveying anything clearly. Most energy/time in this class was spent trying to figure out what he was trying to say every time he opened his mouth. Class average on exams is a failing grade. Even grading scale was confusing. Positive I had a solid B even after horrendous final. Surprised with a B-, might lose scholarship $$

Registered for this class with Ganley and ended up with Keller with no email or anything from Mizzou. Keller teaches like hes teaching to grad students. He responds to questions sarcastically. Doesnt care about his students grades. Tests are way to hard. Very upset with Mizzou.

Ummm, my TA literally helped me pass this course by further explaining. Utilize your TA. Keller doesnt answer questions clearly. Even asking for feedback, its poor. I wouldnt recommend him to anyone. If you do have Keller, STUDY. Even studying wont help the fact that his tests are nothing like the practice and the labs make no sense. Good luck!

He is THAT bad.

This man has the audacity to lecture about a subject, test your skills in lab about things you haven't even seen in class, and test about something utterly different. Honestly, I didn't know how I passed this class. By the end of the semester, you will believe in God.

His lectures are inconsistent to labs and exams. I went to all of his exam prep discussions and he would always end up embarrassing a student; I rarely ever learned something from these meetings. I also didn't miss a single class and took good notes and I always managed to do worse than my expectations.

Never missed a class, did all my projects, and did extra practice and yet this class was unnecessarily complicated. There are rumors that he's been on probation but you'll realize this isn't true. You'd think that he would learn by now if this was the case.

He is passionate about his field and he knows his stuff. However, he will teach something in class and expect you to think outside the box when it comes to exams. There wasn't a single time where a student didn't cry at the end of the exam. As a side note, if you sit next to the aisle, you might get splashed with spit as he walks up and down.

Dr. Keller is by far one of the worst professors I have had here. He is incredibly difficult to follow while he lectures and expect to get tested on material he never covered in class. You need to get a supplemental textbook or something to learn from, because you won't do well just watching him lecture.

DO NOT TAKE KELLERS CLASS. im a pretty good student, most As, sometimes a B. i ended with a b+ ONLY b/c i did great in labs which are grades by your TAs. tests are impossible and as much as you study, the application to the tests just dont add up. your grade will drop with every test. his lectures (zoom or recorded) are messy/hard to follow

Do not reccomend at alllllll!

He has not made many students happy and has a terrible reputation. Would not recommend. He does not seem like he cares for his students. Steer clear of this professor.

Honestly the worst teacher I have ever had. The people who pass the class are the people who are just naturally good at chemistry. I am an A and B average student and I may have to take this class again because it won't count for credit. I have not learned anything and no matter how much work you do, his tests will always be hard. Good luck

Awful teacher, never replies, never helps, most unorganized class I've ever taken and I went to PUBLIC school. Keller is just someone who should never be a teacher and genuinely won't help you if you're struggling. Don't even bother asking your TAs for help, Keller doesn't tell them anything either.

Keller is the worst professor I have ever had. I wish I could give him a 0 because he was such a bad teacher. If you try to ask him a question, he is rude and he answers sarcastically. He thinks so highly of himself and has such a god complex. He needs to be fired in all honesty but he won't because he has been there for so long. Good luck

He should not be teaching a lecture hall because he does not know how to grasp students without a one on one discussion. He is sarcastic and very rude when someone asks a question in the class. He likes chemistry, he just doesn't know how to teach kids that aren't good at it. And he gives us way too much busy work. His tests are beyond hard.

He loves chemistry but he cannot teach it. He really only teaches the kids that already know what is going on. He is available outside of class, but he doesn't answer the questions you ask. If you ask him to go over something again, he won't because "he already went over it." He also has bad handwriting and awful notes. He goes over lectures fast

Professor Keller is not a bad person however he's not a good professor. His lectures do not teach the topics well. The worst aspect of his class were his exams because they had nothing to do with the lectures. He made all his exams purposefully extremely difficult.

Did not enjoy this class at all. Even my TA agreed that he did not teach gen chem in our gen chem class. We learned organic chem in Chem 1100. The online textbook wouldn't work sometimes and his handwriting on the lecture notes was sometimes really hard to read, which obviously didn't make things any easier. All the lectures were recorded, tho.

Holy hell. He is the worst professor I've ever had in the entire time I've been in college. He goes over the basic portions of his material and tests you like you've studied it for WEEKS UPON WEEKS. I'll tell you why you have a large amount of people dropping chem. It's because you make students put in so much work for a 100 LEVEL CLASS.

He poured a lot of passion into his lectures. I really loved learning the basic materials that he covered. Unfortunately his tests are beyond complex and cover far more than what he offers to study. Youll have to do more than just studying homework, having good notetaking skills, and attending lectures to be able to pass his tests.

he was an absolutely horrible professor and I feel as if I got nothing from this class.

You need to know more than just the basics. When studying you have to know things inside and out. Most students take this class twice.

Prof. Keller is by far the worst teacher I have ever had. I am a transfer student so I have had my fair share of hard teachers. His lectures are dull and boring. Exams are very hard there is no way to actually prepare for one. This is a weed out course! Avoid Keller!! Good luck you need it! All the other negative reviews are true! BEWARE!

I've had professor Keller twice now and both classes I've had have been horrible. His lectures are all over the place and there's a lot of homework that takes hours to do each week. His tests are even worse. I hope I never have to take his class again as he has been the worst professor or teacher I've had. The labs are horrible with no instructions

Professor Keller is a nice guy but his lectures are all over the place and dont cover everything you need for the exam. For me i practically live in the building where the TAs and Keller had office hours and Im still barely passing right now. The labs are very time consuming so is the homework. I spend about 6 hours a day on this class.

Seriously so disappointing. I was really excited to learn at the beginning of the year. I only have to take Chem1320 for my degree, but he treats this class as if it's a 4000 level class. Tests aren't weighted, study guides are useless, and communication is very poor. Lectures are dry, and his tests are created with no regards to the student.

Keller is bad at lecturing, and the tests always seem like they have things that are never taught in class.

Is the worst professor that I have ever had. Makes everything so much un needed work. This class was my thirteenth reason.

Lectures bounce from topic to topic and don't follow the structure of the textbook. The only positive thing was that the textbook was online and easy to access. Not helpful with study materials for the test and the tests are not usually about the material discussed in class. Lectures were however posted online which was helpful.

Worst chemistry teacher at Mizzou. Tests are hard af and he gives so much homework and the labs are so time consuming.

This class is not what you would think an introductory chem class would be. Very difficult and teach yourself most of the material. If you have taken previous college chem classes you will be okay, but still struggle some. Try to find previous test other than the one he gives. Haven't figured out how to study yet.

Pros: 1. Nice and enthusiastic guy 3. TAs were helpful Cons: 1. Tests were bad (Lots of unnecessary trickery) 2. Pre-labs were bad (labs were better) 3. Poor at teaching (Highly irrelevant conceptual topics) I took this class 4 yrs ago, and I can safely say it was my hardest class. My only C+. I still love chemistry, but that was a huge blow.

This is by far the worst class I've ever taken. I had 100% in labs and assignments, but couldn't pass a single exam. If you can take this class with anyone else definitely do it because this was not worth it at all. Really regretting not taking it in high school.

A a lot harder than an introductory level chem class should be.

Keller is the worst professor imaginable for a chemistry ONE course. The topics are simple yet the way he taught it and the way he forms his test questions are nearly impossible to understand (even the TAs agreed). Hes a great guy and passionate about chemistry , just the worst professor Ive ever experienced, and completely unapproachable.

professor keller himself seemed nice and his lectures werent bad but outside of this, the class is terrible. i relied heavily on hw assignments to teach me the lessons that would actually be tested. exams are extremely difficult if you didnt know chem before and i failed every single one. if youre taking this class, good luck youll need it.

He is a horrible person and a worse professor. Do whatever you can to avoid this class. He was so rude and shamed me in front of other students during office hours for not understanding a concept we covered in class. This class was detrimental to my mental health, and I advise anybody considering taking this class to STAY AWAY

Every single bad review on here is spot on, and this is by far the worst class I've ever taken. The tests are killer and will leave you fighting to save your grade and sanity. You will not be given any kind of material that even comes close to the test material so take the practice tests he gives you with a grain of salt. DO NOT TAKE THIS CLASS!

DO NOT TAKE!! I repeat, DO NOT TAKE HIS CLASS!

Keller is a super nice guy and he's clearly enthusiastic about chemistry. But the lectures/lab/homework don't help for the tests. Don't take this class. If you can wait until another prof is teaching then I highly suggest that. You'll be fighting to save your grade the entire semester.

Test averages were all Fs and he didnt do anything about it

Keller seems like a nice guy and the material seems understandable until you take the first test and realize it has hardly anything to do with the material at hand. Thinking about this class makes me nauseous and discouraged me greatly

Keller wouldn't let me turn an assignment in late when I had a death in my family. My family member died on a Sunday when our Aleks was due. He told me that "I had all week to do it so it should have been done already." Terrible professor and terrible person honestly.

Exams are unnecessarily hard. These kinds of professors crush dreams and work ethics.

This class seriously stole all my passion for science as a science major. Left me feeling inadequate, frustrated, and like a failure. I've always been an A student, studied about 10+ hours for exams, and still failed. Literally sent me back to therapy. He's a passionate lecturer but gets off on making his tests have nothing to do with his lectures.

Exam's will be unclear and nothing like previous semester tests. Note taking is hard to follow.

Keller is very passionate about chemistry, but not a good teacher at all. He uses random problems and numbers which makes lectures every confusing. Labs dont correlate with course material. Homework isnt helpful. He didnt even respond to my emails. Basically, learned his whole course in the first three weeks of chem 1330 easily. Horrible teacher

Hes a very smart guy but not a great teacher. Look for outside resources for better explanations on topics and rewatch lectures.

Awful tests, decent lectures. If you took ap chem youll get an a, if youre a stem major youll get a b, if youre anything else, good luck.

Take any other professor. If all other professors classes are full, wait a semester. You cannot trust this man. He holds review sessions where he misleads students on what to know for the test, but the tests are very abstract. You will be tested over very specific questions which you have never seen before. Heads up - first test is insanely hard.

Very very tough professor. Loves what he teaches and is a good person but not a good professor. Even with perfect attendance it is easy to find yourself lost in what he is teaching.

Keller has crushed my dreams of continuing my career in stemThis class is like nothing else. His lectures are all over the place, he never finishes a topic and you have to teach yourself all of the content. He seems to be very passionate about chem but forgets that this is an intro class. Tests are hard and dive deep into concepts barley covered

I honestly don't know why the university still allows this guy to teach. It's an intro level, yet he makes the tests more difficult than anything you'd see in a 4000 level class. He's all over the place in lecture, so it's frustratingly difficult to know what he's talking about half the time. Take chemistry at a community college if you can.

You thought this was an intro class, lol.

I stayed up and spent the night in Ellis so many times. Studied for HOURS and way too far in advance just to get 50s and 60s on the exams. If you get Keller just give up and get plastered instead. Better living your life at Willies instead of at your dorm crying!

I would prepare for his exams up to 5-7 days in advance, studying everything that I possibly could. Even though all the time and effort I put into the class meant nothing. Keller doesn't set his students up to succeed. I do not recommend ever taking a class with him and if you have the option to take it over summer then do that.

Keller is a nice guy overall but his exams are horrible. I only got a B because I made sure to stay on top of my labs, small group, and homework assignments. The average for the tests never goes above a D. How you know his tests are hard is when you go to tutoring and they don't even know the answer.

Broke my heart. I was a pre med major... wanted to be a doctor. Now I'm a business major.

If you have this professor here is what you need to do: TRY TO TAKE ANYONE ELSE. When that doesn't work pray you get a good TA and rely on your lab and homework grades. These tests are impossible it doesn't matter how much you study he will throw in topics not covered in lectures. Lectures are sporadic and don't help on tests.

Keller has a reputation throughout mizzou and it is well earned. His tests are extremely hard. He is very passionate about chemistry but sometimes that can lead to him skimming through certain topics which results in the whole class being lost. Be prepared to not have an A. And go to all of the labs, that's your only hope for improving your grade.

Tests are very hard. Lectures are all over the place, and during the week of a test there is a huge workload. You have a lab due, about 5 homework assignments due, lectures, and a test to study for. His lectures are all over the place which makes notes hard to understand and study from. Tests are hard, lab does not go with lecture until weeks later

extremely difficult.

I put in more work for this class then the rest of my classes for the YEAR combined. Extremely hard- spent every free second on this class and still couldn't get an A... Tests are not weighted and the averages are all 55-60%. You can study every single line of notes and practice exams for days and still will struggle ot get above a 70% on exams.

He explains what formulas are and not how they relate to each other and references concepts for other classes constantly rather than staying on task, so be prepared if you are someone who learns this way to form study groups or hire a tutor. He is very intelligent, but he can't bring it down to an introductory chem level.

Keller is knowledgable but horrible at conveying his knowledge. 100% the worst professor/teacher I have had. He over explains things that are too complex for the class to grasp and then skims over the foundations for these concepts. I feel cheated paying for this class because I am teaching myself everything and hiring a tutor to pass.

The worst teacher I have ever had since I have been in school.

Everyone loves him until the first test

Everyone loves him until the first test... Incoming freshman beware

Worst teacher I have ever had. DO NOT ever take chem with him.

It is clear that professor Keller is extremely passionate about chemistry, however I definitely do not recommend taking his class. The exams are awful and look nothing like the homework or material discussed in class. If you like crying take Keller's class.

This class was by far the worst class I have ever taken in my life. The tests are near impossible. The labs are ridiculous. Dr.Keller is quite possibly one of the smartest people I have ever met. However, that does not make up for the disaster this class is. This may be the class that takes me out of STEM. Does not update grades.

Dr. Keller, although he knew the material, struggled to explain it efficiently and often gets sidetracked when teaching. He is very bad at updating grades on time, and his tests are nothing like what you get in the lectures. Good luck to anyone taking his Chem 1 class.

He clearly cares about research and wants you to care about chemistry. Unfortunately, he struggles greatly with the entire teaching aspect. Tutoring alone got me through. Once told me in response to a question "It's not magic, its chemistry. I put the numbers on the board bc they made sense" Do not recommend

This man just speaks words, half of the time doesn't even make sense

He teaches the class as if we have doctorates in chemistry, even though this is an entry level class. Anyone that doesn't have background knowledge in chem, good luck to you. Practice exam is nothing like the actual exam. Very last minute as well, not enough time given to learn topics. He teaches stuff the day before the exam.

Even in an upper level class he was an awful teacher. I'm sure he knows his stuff, he seems like a very smart many, but he cannot teach for his life. The practice exams included topics that were sure to not be on the exam, it was never clear what would be asked of us on the exam, and he would do theoretical problems that made no sense.

This class is awful. Keller is the absolute worst. Half the material he presents is hypothetical and will fly over your head. The exams are completely unfair, the lab rubrics are constantly being revised and handed out right before it's due, there is ZERO communication between him and the TA's. Our test average had to be curved 20% so we could pass

Keller is honestly the worst professor I've ever had. It's like he wants us to fail. He gives us no time to study for exams, is not helpful when asking questions, and will quite literally laugh at you when handing back an exam if you don't do good (happened to me this year). Overall, do not take his class if you want to keep your sanity lol

The rumors about him are 100% true. His lectures make zero sense and his tests do not follow his lectures. He is an extremely hard grader and will take off points if key words aren't used. He does not give you any time to study, as he teaches new material a few days before the tests. Goodluck.

You will "learn" the material for the test the class before. He doesn't follow any section of the book and leaves you wondering what the test is even over. His lectures jump all over the place. He is a kind man, but a really bad professor. There are multiple opportunities to contact him through office hours and other times however.

He rambles too much and doesn't provide sufficient explanations on topics. He is very unclear on what is going to be on exams. If you want to learn you have to teach yourself outside of class.

He has the name Killer Keller for a reason. His lectures you learn nothing pretty much and the best way to do good on the test is by reading the textbook on your own before the test. The test questions are terrible too, he shouldn't be aloud to write a test. Also at the end he hits you with a group project to work on outside of class which sucks.

This professor does not actually teach. He talks at you in a rambling way and makes fun of the few brave students that actually ask questions. The entirety of the school, including people not taking the class and other professors, know him as "killer Keller" -- and with good reason. Calling the man a teacher is offensive to teachers everywhere.

This professor stands true to his given nickname of "Killer Keller". He often leaves his students and TAs confused about what they are supposed to do in the lab. His exams are over things that you are either taught about the class before and are presented in ridiculous ways that makes it hard to understand what he's asking you to do.

Dr. Keller is incredibly intelligent, has dope fits, and he genuinely loves chemistry. However, it should be illegal for this man to write exams. Some things I saw for the first time on exams. He also is so disorganized that it is somewhat impressive. If you didn't have to take any of his classes, I am sure he would be awesome.

I've never met someone more condescending and rude in my entire life. Killer Keller lives to his name again. Absolutely slaughtered my GPA.

I would sooner drop a class that he is teaching than give it a try. HE DID NOT TEACH THE FUNDAMENTALS OF CHEMISTRY WHATSOEVER! Unless you have already taken a chemistry course, can read his mind, and are able to sift though his disorganization- do yourself the favor and do not take any class he teaches. Tests would have new material on them too...

This class is extremely hard. The exams have questions over material that hasn't been covered yet. The wording of exams make it difficult to understand what is being asked.

He literally told me he didn't know how to do the quadratic formula. THAT LITERALLY THE BASIS OF ALL THE MATH ON EXAM 2. He also "doesn't like power point" and scribbles down his notes on the projector. That is personally not my jam. But seriously, if he would just use powerpoint slides or something similar for his notes, he would be much better.

His lectures consist of him drawing arrows, circling, and scribbling all over the place. It is impossible to read let alone understand the notes by the end. If you have to take any of his classes, take them online somewhere else. Topics on the exams are often introduced the week AFTER the exam. The textbook and youtube are the only way to pass.

If you can take this class honors or with literally anyone else, do it. This caused way too much unnecessary stress. The TAs and homework points are the only reason I have a decent grade.

This is my first time having Keller in any of my classes, and thought that everyone was just lying. I came from a background of harder classes in high school and a heavier workload with only one or two Bs in my life. WRONG. Exams are nothing, literally nothing like the lectures. ALEKS system has insane amounts of homework. DO NOT TAKE.

He is nicknamed Killer Keller for a reason. Tests are horrible and make no sense and include none of the material he rambles about in class. Honestly don't know how he hasn't gotten fired because of how many students fail his class. This is an entry-level class and he acts like everyone is a chemistry major and knows everything. horrible.

Keller is completely unfit to be teaching this class. His lectures are incomprehensible and he only covers content a week after you already taught it to yourself from doing the homework. The ALEKS site is frustrating and he assigns a ridiculous amount to do each week. Tests never have anything to do with class. Do not take here.

Keller is extremely disorganized, making everything more difficult. Youll teach yourself everything in this course, because of careless errors in everything. Exams are nearly impossible, with errors and questions on content you haven't learned yet. Youll second-guess everything in here like you are being gaslit. Youll spend 300+ hours on homework.

-Harsh grader -Labs don't correlate with lecture -Test has nothing to do with lecture -Doesn't explain things well -You and your TA will be confused in the lab -Only grades the hardest questions in lab and gives no credit for the easier ones

reviews and labs don't relate to the exams, he rambles on during lectures and jumps from topic to topic, his handwriting looks like literal scribbles most of the time. He seems like a nice guy but a HORRIBLE teacher for an entry level chemistry class.

If you are able to take this class with anyone else you should. Extremely hard and test heavy and not very helpful during office hours. Lectures are hard to follow along and the tests are like 20 question MAYBE so you have to get so many correct. Also does not provide a study guide so hard to know everything for the test.

Horrible prof, doesn't even teach relevant content and study guides do not relate to any of the text content.

If you take this class you better know how to follow along to tagents that dont go over anything thing on the exams.Also don't try and study the pratice exams they are nothing like the actually exam.

Between him rambling and trying to read his awful handwriting it is almost impossible to take any helpful notes. There is no point in studying the practice exams he provides because they never turn out to be like the actual exam. The only reason I am barely passing this class is because he gives assignments that are easy points.

Be prepared to have no idea what's going on and most likely rely on YouTube. Half the time you don't even know what you're learning because the notes do not correspond from day to day. He also grades assignments very differently. I don't know if it's the TAs or him, but they're a lot of test discrepancies

worse professor r Ive ever had, every time I emailed him he always had a very smart remark and gave me attitude when I asked for an extension on an assignment to go to a funeral. Didn't give me an extension. TA was absolutely awful and I missed one lab and he bashed me in front of the whole lab about how I didn't go. Made me not want to come back.

Oh my god do not take this class unless you want to walk in to lecture and feel like u just go slapped in the face. I wouldn't even call his lectures “lectures” I'd call them rambles. The only thing that got me a decent grade was getting access from previous years tests and studying for 10+ hours for each exam. Prepare to be stressed out.

Aleks is nothing like in-class lecture problems and his Test are very difficult.

I thought he seemed really nice and seemed to be a good professor. Turns out he just going on tangents in class and doesn't talk about what is actually important information. In class seems easy and understandable yet the tests are about stuff he never even mentioned once in class. ALEKS is not a good resource or teacher either.

I have not even finished this man's class yet and I am pissed. When I tell you Steven Keller does not know anything about teaching. Yes, he is a smart guy who knows chemistry, but he cannot translate this for beginners. I have never been so enraged by homework because he has never taught us the problems, nor does he acknowledge this.

I'll keep this as straightforward as possible with the limited word count: Lectures are unorganized and difficult to follow Tests are more difficult than the material learned in class Lab is absurd and it seems like Keller and the TAs don't communicate If you want to learn BASIC chemistry, you will not learn it in this class (i.e. use Khan Academy)

This class is extremely disorganized. He jumps from topic to topic without building a foundation at the beginning. The tests have nothing to do with what is talked about in class and there is no structure. He does not teach but rambles. You will be teaching yourself most of the time. Kahn Academy and YouTube taught me everything.

The class is disorganized, and lectures are disjointed meshes of whatever Prof. Keller feels like talking about at any given point. He is extremely passionate about the topic, which could make him highly engaging but in this case only makes him struggle to be accessible to students who are not advanced in the field. Do not take this class.

Been suspended for academic issues before absolutely do not take

Steve Keller has been on probation before and Im not surprised by this at all. He deserves to be fired, he doesn't provide/teach you any of the tools you need to pass his tests.

Tests are nothing like the textbook, lectures, or homework. Be prepared to teach yourself everything and study for days just to leave the test feeling like you failed. Calculation test questions barely give you any info to work off of.

Worst teacher ever. If you've never had chemistry, avoid this class. Tests have nothing to do with his lectures, and practice exams are useless. A test every three weeks is crazy—you won't learn. Attendance isn't required, but group projects are graded, so it basically is. Unfair grading, unclear expectations. Avoid!

he has been on probation bc he struggles to teach and you basically have to teach yourself and his writing in class is just a bunch of scribbles

If your major does not REQUIRE you to take this course, for your own sake do not take it. After hours spent in office hours and tiger tutoring, my test grades still have not improved. Everything on the test is application based, and a majority of the tests do not correlate to the lectures.

I went into this class knowing that Dr.Keller was a tough proffessor and mentally prepared for that but i wouldent say there is a ton of hw. I use the hw as a studying tool and that helps. The test are much more indepth then what he teaches therefore you may want to take those extra steps on stuying.

This was the worst class I've ever taken at Mizzou. Keller rambles during his lecture, and never come full circle with the point. I was confused af. The exams are not multiple choice and you will struggle.

His lectures are disorganized and useless. He lacks any ability to take accountability. He typically blames the students for their poor performance without being able to acknowledge that he might have taught a subject poorly. Wait to take chem 1 through Ganley or just take it through a community college to avoid having to interact with this man.

Don't bother attending his lectures, there is no structure to them and he explains literally nothing. Do the ALEKS homework, it's worth a lot but don't think it'll prepare you for the exam they are nothing like what you do on the homework. Do the practice exam diligently and pray

I only took this professor for lab, not lecture. Holds about twice as many labs as other chem professors. Ridiculous grading criteria, expects professional level accuracy, and if you do not do everything perfectly, good luck getting a good grade. Labs are also not useful for the class; essentially a waste of 3 hours a week doing busy work.

His lectures are... confusing at best, the only good thing about them are how clear it is that he is passionate about what he does. His "office hours" are worse, he answers questions in a very roundabout way where you forget what you question even was by the end of him answering. Class is very ALEKS heavy, rely on your TA's and classmates instead.

He never responds to emails and always has a line of people asking questions after lectures, so it's hard to reach him. Hard to study for exams and do homework when topics are not discussed in lectures. Showing up for class matters even though he doesn't take attendance, as you will be clueless otherwise.

Not good professor. Wait until you can take the class with a different professor. His lectures are disorganized and random, often not relating to test content. Save yourself pain and suffering and take it with a chemistry professor that teaches in a way that promotes learning, rather than confusion and anger.

Keller's class is extremely test-heavy—there are four exams (with the lowest one dropped), and the final, which constitutes about 70% of your grade. While some questions are related to the material covered, many feel random. Always have your tests reviewed by Keller, as they are often graded incorrectly by the TAs.

I did not receive a single exam grade back that was accurate to what was put onto Canvas. Additionally, we are allowed a drop for our lowest exam. Instead, my HIGHEST exam was dropped putting me in a situation worse than before. I studies weeks before each exam but each question was unpredictable and no where near what was put on the practice exam.

This professor is passionate, but not a good teacher. His material doesn't relate to the exams, which can be random and confusing. Practice exams were unhelpful, and I often failed despite studying. If you must take this class, consider online or community college options. I won't take another chemistry class with him. Beware of a lot of ALEKS hw!

Don't take a Keller class. It's absolutely terrible. He is not good teacher. He just talks to entertain himself and you will be lost 90% of the time. Also, he doesn't think he is the problem.

Legitimately one of the worst classes I've ever taken in my life. The practice exams look 1000% different so don't even try to study from those. I had friends who had the other professor (Ganley?) and their tests were exactly like homework problems and got a cheat sheet for exams but we got none of that. Do whatever possible to not take the class!!

This was legitimately one of the worst classes I've ever taken in my life. The practice tests are nothing like the exams so don't even try to study from those. I had friends in a different professor's class (Ganley?) and the exams were all homework problems and they got cheat sheets for all exams. Please do whatever you can to not take his class!!!

No extra credit. Grade is only tests and homework. I worked so hard and studied for days before each test and went to tutoring and barely passed the class. This class is set up for you to fail do not take it. Keller is a nice person but not a good entry level teacher. Don't recommend.

Do not take this professor for chem. He is passionate but his lectures are almost impossible to follow, his system of note taking isn't helpful, there are exams every 2 weeks it feels like and no matter how hard I study I always did poorly on exams. I would not recommend this class to anyone.

This class is extremely difficult and the tests make up a huge portion of your grade. The practice tests are a joke and the lectures are hard to follow. The homework takes hours to complete and has nothing to do with what you learn in lecture or on the test. Take Ganley if you can.

Lectures and homework did not correlate at all to anything on the test. Very hard to follow, went to very many tutoring sessions and studied for hours, ended up with a C. :(

Absolutely one of the worst professors at Mizzou hands down. Unfortunately he's a very kinda man and I know he's intelligent but he is NOT a good teacher and can not clearly communicate ideas and almost never has his lectures be helpful for his exams.

Do not take a class with Keller. I promise you are better off waiting a semester if needed and changing your schedule around to avoid having him. He gives you practice exams you can understand then makes the entirety of the actual exam a trick question compared to it. You will at least one question on the real exam you've never seen before.

He is awful, I went to 4 different tutors for what was supposed to be a Chem 1 class. But in those meetings they informed me, They didn't know how to help, and that I needed a bio chem tutor instead. No student should have to feel the way they do in Kellers class. Please take my suggestion and get a different professor you will thank me later.

he is a terrible teacher and expects you to already know the subject. was put on probation a few years ago and somehow they hired him again. take anyone else but him

Avoid at all costs.

He is not a good educator.

Genuinely if there is any way to NOT take this guy please do. Taking this course is like paying to teach yourself. The lectures and studying for his test is like putting together a puzzle, you are constantly guessing what is going to be on the test. He rambles on and on and dances around topics without ever fully covering them.

Every time I would have a problem I would email him about hey times are tough and stressful and I accidentally missed the first assignment can I get an extension by one day and he never responded tried again and silence so when I wrote he was a bad teacher he then emailed me telling me to try his office hours and guess what not even there to help.

DO NOT DO IT!!!!!!!!

You are literally teaching yourself everything and doing a puzzle to try to figure out what he is even talking about and how any of this relates to the test or materiel He goes off on tangents in class that make no sense so you are really just shooting in the dark when studying. genuinely find a way to talk this online or over the summer

DO NOT TAKE IF KELLER IS YOUR PROFESOR. he does not stay on task and doesn't teach what is actually on the exams. I shit you not everything I have learned that is chemistry related I taught myself.

You know that surfer dude vine where nothing mad enay sense? that exactly what having a class with keller is like. He is one of the most interesting people I have ever met in the worst way possible, he cannot answer a question, stay on task, or teach. It is honestly shocking he is still employed by the university. Even his own TAs hate him.

worst teacher i have ever had
