Funny and friendly teacher. Very Helpful one on one

tests were pretty long, but he was funny and explained things well. He is formal and expects you to learn.

He goes into great detail in his notes. He tries to be funny but he sucks at it. The homework is average difficulty but the tests will****you and your GPA. Nice guy but if you have the chance take someone else.

Warren is a hard teacher. Most of his lectures are tedious, but sometimes, it does get fairly interesting. He has hard WebAssigns, but if you finish those assignments and do well on them, you'll be fine on his tests. Even though the comments aren't too nice about him here he has a good personality outside of class. Be sure to go to tutorial and SI!

egads. he's kind of difficult in class and his tests are hard. but he's a nice person overall. just make sure you speak to him and are very polite.

Best chem teacher. His test are hard... redo webassigns and read notes. He is hard, but if you like chem it's worth it to have him.

He very helpful and friendly. He has a good sense of humor and a thorough and interesting class period. If students are lazy or rude he may not be as helpful but students should be respectful to their teachers anyway. It is hard, I had a C+ on my first test, but you learn your material. Be prepared to actually earn your grade. I like hi

Cracks HORRIBLE jokes almost daily, dry humor. Hard teacher and comes across intimidating but can be really helpful if need be.

Don't walk out in the middle of class. It pisses him off and he calls you out.

Dr. Warren has a bad reputation at State, which is unfair. I thought he was helpful and he did try to be understanding to those who just did not get it. Some people take his helpfulness as being rude, but that's just his nature. The class is hard and so are webassigns. I spent all of my free time in the tutorial. It was worth it!

Difficult teacher, but it is a difficult course. Tests are difficult but fair in the sense that everything on them has been covered in the lectures. Very challenging and worthwhile for students who are majoring in any sort of chemistry field.

He is a good teacher and fair. The tests are hard, but a little studying will help out. Examples given in class are usually on the test and resemble webassigns. Going to his office hours helps out a lot.

Warren is tough, as I'm sure you can see from the other comments posted, but he is fair. What makes him tough is the fact that he expects you to do work, which at the college level you should be able to deal with. Read his files, go to class, go to SI, read the book. If you're still sinking, GO TO OFFICE HOURS. He's tough, but he wants to help you

Warren is a very hard teacher, but his students will learn a lot. I tried to get out when I first found out I had him, but I'm glad I stayed. Practice tests are just like the tests and the applications are relevant. Use the book and go to class and you'll do fine.

He was not a bad professor.He explained things well.His jokes were corny but he tried to keep the class entertaining.He called people out if they left class early and didn't talk to him about it.Nothing said if talked beforehand.Its rude to leave midclass.Class wasnt impossible.require a lot of time for the homeworks.Dont take if your sensitive.

He is a great lecturer. He takes his time explaining things and the class notes are very useful. He provides you with all you need to know for the test. They are hard, but be is very obvious what material is going to be on the test

He is a great professor who teaches at the college level. His tests are a bit tough, but it is all material that is covered quite well in class

Dr. Warren is an absolutely terrific lecturer. He provides very detailed explanations and applications of the concepts and makes the lecture interesting. The course required 3++ hours of work outside of class per hour spent in lecture. Exams are very challenging. I can say that I learned a lot. I enjoyed his class and would recommend it.

If you are not a slacker disregard all the other comments about Dr. Warren. His lectures are very clear and you can tell he really cares. Pay attention in class and do the Webassign and practice tests. He doesn't try to trick you on tests. If you are not very diligent and procrastinate dont expect any miracles.

A hard class. Dr. Warren is a very good teacher. The practice tests that he passes out a few days before the test are almost identical to the real test so study those.

This professor take a bit to get used to. He explains things using really big words which makes it hard to understand what he is saying sometimes but he usually explains things multiple times before he moves on so you have a little bit to figure out what he means. once you get used to him he is great. He is always there if you need help!!

You'll have to work for your grade, but everything on the tests is gone over in the class and on the homework. He gives out a practice test beforehand that is almost identical, so make sure to do that. Tells really geeky jokes and makes lame metaphors, but he knows what he's talking about, and he genuinely wants to help.

Not that hard. He teaches very clearly. Everyone else is just complaining that it's not high school easy. Do you homework and the practice tests and you'll do fine

He explains the subject very well, much better than I expected based on past comments. Tests were comprehensive but not impossible, and were also curved. Homework was not extremely hard either. Practice tests are almost identical to the real tests and were extremely helpful come test time.

Was warned before class about the difficulty of this course and Warren's tests. When I prepared as he guided, I was successful in his class. I feel well prepared as I continue in Chemistry. Recommend him to anyone taking CH 201.

It can be hard to focus during class, but if you really pay attention to what he's saying when he's teaching you will learn. He does a really good job of walking students through each step to help them be better problem solvers. He's pretty helpful and answers any questions people have. Despite all his haters he keeps a positive upbeat attitude.

Dr. Warren has quite the reputation here on Hate My Professors. Please do not be afraid of taking his class. He explains concepts clearly using slides, and walks through each one in detail. Tests are challenging, but if you put an honest effort into reading the textbook (just do it!), paying attention in class, and doing Webassign, you will do well

Don't listen to the haters, Dr. Warren may have few bad puns up his sleeve, but he is a great teacher, and gives you all the resources you need to be successful in chemistry.

Doctor Warren gets a lot of hate but he is a funny, nice guy who will help you when you ask. You have to work hard for your grade; his tests are long and difficult but he grades fairly. Overall I enjoyed his entertaining lectures and feel very prepared for future chemistry classes.

I took Dr. Warren for CH201 and LOVED IT!!!! Although I ended up with a B in the class, I've never been more proud of a B in my life. The class was definitely difficult, but if you pay attention in class, do the homework, and study HARD for exams you'll do fine. He also cracks really cheesy nerdy jokes which I greatly appreciated.

Dr. Warren is a very nice person and has an extremely odd sense of humor. However, this class was extraordinarily frustrating. He does give practice exams similar to the actual exam, but this class was exceptionally challenging. There is no extra or partial credit, so know your stuff before you step into an exam with him. Wouldn't take him again.

Dr. Warren gets a bad wrap around campus and sometimes it can be justified. But, I had a good experience in his class. His notes are hand-written and not posted online, so there is an incentive to come to class. His examples are very helpful for homework and exams, which are very similar to practice exams. Work hard and study and you'll do fine.

He was always give real life examples and tries to make the subject more relatable to others. I was somewhat familiar with the course material before due to taking AP Chemistry, but if you do the homework he assigns and do the practice tests he gives, doing well in his class isn't too difficult.

Best Chemistry professor I've had so far, and I am a chemical engineering major. Lectures are very interesting, as he relates calculations to real world examples. Several tests were almost the exact same as the practice tests, but not all of them, so know more than just the practice tests.

I think Dr. Warren catches a lot of flak because of the subject he teaches. I am currently in his quantitative chemistry class and it is difficult, but Warren is a fair teacher. He really wants his students to learn and is very passionate about what he does; he does not put things on his tests he doesn't teach, and he does partial grading, too.

I have no idea where the terrible rep comes from. Dr. Warren's class was hard, but really pretty fair. The exams were totally reflective of the lengthy examples he did in class (and similar to practice exams). Just don't get bogged down in his word problems. He's also quite the nerd - which is awesome, if you are yourself a nerd. I liked the class.

Dr. Warren really is not that bad. He's actually great if you are smart and able to understand abstract concepts and his good vocabulary. His explanations during lecture are incredibly thorough and easy to understand. His "practice tests" are almost identical to the actual tests so if you understand those you are basically guaranteed an A.

Dr. Warren is actually not that bad. Especially if your in the college of engineering. I am a senior in computer science and took the class as a pre requisite for dental school. This class is one of the easiest classes ive ever taken at state. Go over the previous tests, they are very similar. Try to find more than one past test to go over though.

Warren's really not that bad if you actually put some time into studying. The practice tests are great examples of what you'll see on the real thing. I found his humor really enjoyable, if a bit dry. This is definitely a class where a few hours of studying before the exam will net you at least a B.

This class wasn't nearly as bad as I anticipated. The material was tough, but Dr. Warren knows how to explain it well. The exams were very challenging, but if you study the quizzes and do the homework, you'll be in good shape. I thought his humor was funny.

Dr. Warren is very entertaining and funny. The class is hard but hes a great professor. He is especially helpful at office hours.

Great guy. Pay attention in class, but he is great for help during office hours or after lecture. Gives real life example and applications of chemistry. I hated CH101, but CH201 with Warren is good.

Everyone who failed the class probably chose not to use his resources. He may do annoying things like not posting notes, making homework due on inconsistent days, and only going through 2 or 3 problems in an entire lecture, BUT he gives you PLENTY of chances to learn. He is great in office hours. He supplies many supplemental docs. Come to class...

Warren is really sweet and is SUPER passionate about chemistry. I'm awful at chemistry but I have been doing okay on his exams (just show up to class, take notes, ask questions, go to office hours). His rating is low because his tests come out of left field, but if you work on his practice exams (and find other ones from past years) you'll be okay!

Warren is a great teacher for CH201. He is extremely thorough in both explaining general concepts and working through specific examples. He very frequently advertises his office hours, so there is no way to be left without help. His tests can be confusing, but are incredibly similar to his practice tests, so spend time on those well in advance.

Warren is a great professor, especially given that the material is so difficult to begin with. He offers multiple resources and is super easy to get in contact with through email or office hours. Be prepared for some Monty Python jokes. Warren really cares about his students and does offer some extra credit on webassign.

His lectures are pretty straightforward. He can go far into detail with things, but it's often relevant and interesting. Has a lot of "awkward" humor but is overall pleasant. Really knows what he's talking about. Practice exams are great representations of the real exams (and super similar too). Go to office hours, he's really helpful there.

Dr. Warren is suck a good professor. His notes are easy to follow and really organized. The only thing is they aren't posted so class is required. He has an odd sense of humor but he is funny at times.

Dr. Warren really cares about his students. Class is madantory since no notes are posted online. Go to office hours and show him that you are willing to make an effort, then he will 100% help you. His tests do have some trick questions, but they are VERY similar to the practice tests that he gives.

Dr. Warren has a much worse reputation than he deserves. His lectures are a bit slow so it can be hard to stay focused, but if you stick it out, his examples really do help you complete WA, and the files he posts are also helpful. He tries to be funny and usually fails, but he has good intentions. Tests are very similar to practice exams.

Okay, I don't know what all the fuss is about for Warren's class. If you actually try you will do well. This class is probably the hardest 202 class but you will absolutely learn the most. Review the practice exams, know them, and you're golden. Takes effort, but worth it. I'm not even good at chemistry but I did well in his class. Take warren!

If you do the practice tests, you can get an A on his tests no problem. He may seem standoffish at first, but as soon as you talk to him, he is very friendly and helpful. Go through your tests and check that your grade is correct because both my friend and I had tests that should have been 10 points higher than what was given(Warren will fix it)

Dr. Warren is honestly an amazing professor. If you speak to him in office hours and obtain help, the course is not difficult. His tests are application heavy, but if you do the work such as reading the textbook and doing examples found in the text and notes, you will pass. Practice tests are also so helpful!

I tried to switch out of his class due to reviews on this site but was pleasently surprised when he turned out to be a great professor. If you go to lecture he works through helpful examples and sometimes goes off on a tangent you zone out for, but overall its very useful. The practice tests are VERY telling of what the actual test will be like.

Dr. Warren is given a bad rep, I'm assuming by people who don't know what a typical stem class load entails. Examples in class are useful for WA but he doesn't have time to go over every type of problem on WA. WAs can be a lot but ALL ch201 profs use the same problems. If you know the practice tests and put in work, you'll be just fine.

Dr. Warren is awesome! I received a decent grade on the first test but on the second test I received a D+. I was really upset and went to his office hours, he was so kind and literally went through the test with me. I was able to use his advice and pull my grade up to an A-. Attendance isn't mandatory, but you will be confused if you don't come.

So, to begin this, I SUCK AT CHEMISTRY!! It's not that I don't try; Chemistry just isn't my forte. Dr. Warren is really tough. His exams are hard. Sometimes I could follow what he was saying but most of the time, I was lost. After finding outside help though, his supplements are super helpful. In comparison to the other profs, he's awesome though.

Easiest stem class I've ever taken. Go to lecture (actually pay attention) and MEMORIZE the practice test/test from last year and you can prob ace the class. TAs change every semester but they were VERY fair graders in my experience. There's usually only one webassign/wk. If you have chegg this class is easy money.

I had Warren during the COVID-19 situation. He is old fashioned, and likes to stick to handwritten notes. He adjusted the course as we progressed in order to make it possible for his students to obtain a higher grade. He is straightforward, but cares about his student succeeding. Old tests are similar to new ones, and attendance is not needed.

If you enjoy chemistry, you'll love Dr. Warren. He teaches you to understand, not to memorize. He's a little quirky, but he truly cares about his students. He gives great real-life examples and exams are very similar to practice tests. Don't be intimidated by the ratings on here. Take this class!

Don't let the other reviews scare you. I took this my first semester, not having taken a chem class in years, and did fine without the textbook. Dr. Warren lectures are crucial, his notes are also an exact replica of the test. Pay attention and you will do well. Very dry humor, but going to office hours is very helpful too if confused.

Dr. Warren provides all the materials to teach you - textbook, examples, help files and audio lectures. He will prepare you to teach yourself material for the MCAT, PCAT, DAT, etc. Warren is not going to spoon feed material, but he won't leave you to dry when you're lost. He answered my numerous emails about homework within the hour.

This is the 2nd course I have taken with Dr. Warren and can vouch that the comments here are NOT reflective of his quality as a teacher. 201 and 202 are difficult courses and can dismay students no matter who the professor is, but Dr. Warren does a great job giving in depth explanations and being available to answer questions outside the classroom.

Began doing online zoom lectures twice a week which were incredibly helpful. Class structure can be rough, with three tests and final exam which make up pretty much your entire grade. With that said Dr. Warren is a passionate professor who tries his best to help his students learn. Very receptive to questions and will not leave you hanging.
