Great guy, responds to student feedback, puts in the extra hours to make sure students get the material. OChem is a hard class, but this man makes it simple and straightforward.

One of the best organic chemistry teachers you will have. Explains everything in great detail and makes sure everyone understand no matter how many questions are asked. He is hard, but only if you make it hard. Do all the reading and all the homework and understand it all, you should be good. THIS IS THE TEACHER YOU WANT FOR ORGANIC CHEMISTRY.

If I could take Professor Casselman for the entire 12 series, I would. Awesome professor who will do everything he can to help his students succeed. If you're trying to decide between which professor to take for ochem, do yourself a favor and choose Casselman. Grade based on: 3 exams (equally weighted including the final), lab, and participation.

Good teacher! Cares for student! Do hw, attend lecture and get your clicker points. Get at least a B. Nice curve. Got a C because of finals and midterms being on the same day as BIO. But he is really nice, go to office hours if help is needed! Great guy!

The absolute best professor for the subject. Extremely fair grader and very clear in his lectures. Don't be afraid of Organic Chemistry, it requires hard work but it is definitely possible to get a B or higher. Think of it as puzzle solving and less strict memorization.

Great professor who cares about the progress of his students. He moves at a good pace and even uploads supplementary material just to make sure you don't feel left behind. Clicker questions are challenging and helpful. Very patient professor and gives great feedback. Work hard and you'll get the grade you deserve.

Casselman is honestly an angel. Ochem is not an easy course no matter who you take, but he does the best he can to get you prepared for the rest of the series. His lectures are very organized & detailed. He always posts all the notes online and he'll post supplementary videos online to help. His midterms are very fair. 10/10 would recommend.

Believe me folks, Matt Casselman is a TREMENDOUS professor. He is a smart, incredible guy. VERY high energy. He wants you to succeed BIGLY. He hosts 2 review sessions per exam, creates supplemental videos to help you, and does in-class activities to help you get proficient with the material. He is truly going to MAKE OCHEM GREAT AGAIN.

Amazing professor would definitely recommend. There are three midterms, no final. The third one is given during final time, but it's weighted the exact same as the other two midterms. His curves changes depending on the averages of the tests and the practice problems he gives actually help and are not mandatory!

Dr. Casselman was the best professor I have ever had at UCR, even though I tend to struggle in chemistry. He went out of his way to help me succeed and went above and beyond to help. If you're going to take OCHEM at UCR, take Casselman. You won't regret it. HE GENUINELY CARES AND WILL HELP YOU PASS if you ask for help. Amazing professor.

Honestly, Pro. Cassleman is a great professor! He is really good at explaining concepts clearly. Also, he is patient. He has just 3 midterms and no final. During finals week you take the last midterm. I wish I could take him for chem 12B. He is the best professor out of all the other professors who teach ochem. Make sure you take him if you can!

He is the best alchemy teacher in the department! He explains everything really clearly and posts all of his notes online if you miss s also super nice and will add points to your tests if he thinks the TAs were being too hard (which is always). He truly cares about the students.

By far the BEST professor I have ever had for any class ever in my whole life! Highly recommend him! He really cares about the success of his students. He explains difficult concepts so clearly and well, and is so approachable. His tests are hard (It's ochem so come on) but very fair. Don't take anyone else for Ochem!!!!!

Best chem teacher ever. He does not trick you on his exams, you won't get anything that he didn't specifically go over in class. Don't need the book to study. Tests are fair and pretty simple. Love this guy and this subject

You must attend every lecture because although he posts ppts, they are lacking the details he gives in class. The tests are straightforward and not meant to trick you like other ochem profs. He does clickers and online quizzes too and makes his own cute videos explaining stuff. Definitely one of the easier ochem professor choices. I'm sad to leave

He is by far the best professor I've had so far at UCR. His videos are really helpful, and he is very accessible. He will help you understand any questions you have, and he will even give you partial credit on problems you got wrong on tests if you explain why you did what you did. However, his tests are hard and they are all free response.

Can't deny that he's a good professor, but he's over-hyped.

Great professor!!!. Lectures are helpful because he explains well. Very helpful during office hours. The material he covers is not impossible to understand but you need to do lots of practice problems on your own. He has in class worksheets almost ever other week. 3 midterms that are free response and he gives practice midterms as well.

Very fair in exams and very clear lectures with extremely helpful worksheets. His office hours are of tremendous benefit so it is well worth your time to go! My only problem is that the textbook problems he assigned (optional) were a lot more nuanced and difficult than exams (though some problems are fair). He also said I could win a Nobel Prize!!!

BEST PROFESSOR EVER. Videos are super helpful. Don't be afraid to approach him in office hours, he's really kind and will answer all your questions. Chill dude. Exams are tricky though so you have to study a lot. Made me like a chem class for once. Don't need the book. Make sure you understand his practice tests and lectures as well as videos

He gives four midterms, no final. He is funny and nice. He gives activity mostly once a week, he really teaches things. Very helpful.

Though he doesn't explain as much as he should, he's a really good ochem teacher and it shows. there was 3 midterms and a final. As long as you do average or above you should pass.

Take him instead of Martin for any ochem class. I had Martin for 12C; got C. I felt more motivated when I took ochem with Casselman, and that DID help (B+). Anyways, there are people who his tests are easy, but overall, they are just egotistical .DON'T USE CLUTCH PREP. You WILL fail if you use that!! Sarah, who taught F,W,S17 was a poor SI leader.

Had Casselman for Ochem 8A and 8B. He's probably the best of the ochem professors but he's still hard. There barely a curve but as long as you understand his notes, practice problems, and the practice test its straightforward. Tests basically make up your whole grade.

I had him for 8A and 8B. He is better in 8A as of more prepared. I bet he will be as good when he does 8B again. He want students to actually learn and think, not memorizing. If you don't want to learn, then choose another prof. I have great respect on him and his efforts for tutorial videos, worksheets, practice exams, and office hours. Love!

You're going to struggle in ochem, as it's not an easy subject. That being said, Casselmen tries his best to help through his videos, his in-class activity worksheets, and office hours. STUDY AND PRACTICE FOR YOUR EXAMS, they make up 85% of grade. Avegare is high 50%, so that says a lot.

BEST ochem professor available at UCR. However, this class is still intense. Everyone says ochem is hard, but the set up of the class institution-wide is a mess. The lecture covers everything important, but you absolutely will be teaching yourself the bulk of the work. Be ready to study like you've never studied before - find what works for you.

Casselman is a fun professor. Super nice guy. His exams are pretty straightforward... and remember the answer is always resonance. Extremely accessible and he has online office hours before his exams. You do have to practice to get a handle on the material, but that's the case regardless of what professor you have.

Casselman is probably the best chemistry professor I've had here at UCR. I went to office hours a couple of times just to get a better understanding on some concepts. I would say to go to class because you want to know how HE expects you to learn things. Review the material after every lecture! If you keep up, the class isn't as bad as you think.

The most engaging and kind Organic Chemistry Professors at UCR. He is patient and intelligent, as well as, seeks to understand where the student is coming from when they asking questions. Although he grades tough I would say that he is strict but fair. His expectations are very clear for the entire class. One of the BEST professors at UCR!

Pure memorization is just half of it. You have to conceptually know what you're doing which is what he expects from you. I highly recommend going to SI as they have practice problems that help you think outside the box. Casselman was pretty straightforward in this class for reactions. Also made the cumulative portion of the final exam pretty easy.

Took 8B too. Really good lecturer. Learn the mechanisms. The problem sets are essential & good for practicing. Review activity day worksheets & study his slides, sometimes he will literally copy & paste question(s) from them as an exam question. Go to office hours! He's good at walking through problems and figuring out what you don't understand.

took him for the whole series. Hard class bc of the practice and memorization you need to do, but he's straight forward on what you need to know. Overall, he's great

Dr. Casselman is an excellent professor. Ochem is not an easy subject but he explains things very well. Never felt like any of his tests were unfair with the material presented. I will say that the tests are usually pretty long and to fully complete them in 50 minutes is more challenging than the material itself. Just go to his office hours often

This guy gives you solid knowledge if you put in the work. His exams are all written and is a picky grader. Keep up with all the lectures, practice problems, practice exams, etc. I honestly feel that he's a bit too difficult; I hardcore studied for this class and still only managed to get a B+. Lots of people failed. He's not worth the hype.

I took Casselman for chem8A and loved his class so much I'm taking him for 8B. His lectures are well organized and he provides outlines which are helpful since ochem is a lot of drawing. He provides a lot of resources to do well in his class because he doesn't curve as heavy as other professors.

Ochem is hard no matter who you take it with. for context, I barely passed chem1c and ended up with an A in ochem. Just studying will NOT help, make sure you DO PRACTICE PROBLEMS!!! I used the practice exams he gives, Si worksheets, and textbook practice problems. Knowing what to memorize and what to understand led me to my A.

Casselman is an amazing professor! You do have to put work into this class to have a good outcome but he will work with you to make sure you know the material! We had 8B online and he was very understanding and accommodating for the students. Go to office hours, go to lectures for poll questions, and study the material !!

I love this professor! I had him for 8A and a chemical research study that he had conducted for 2 weeks. He has been my favorite professor ever. I genuinely enjoyed ochem! Everyone fears "ochem" but professor casselman has made it beyond encouraging and his notes are organized and color coded which make it easy for me to learn. TAKE HIM!!

Professor Casselman is one of the best professors I have ever had! It is a difficult class but he does an amazing job at explaining everything and he is very accessible outside of class. He is so nice and really cares about his students, he always says he wants to see us succeed and if we all deserve A's, he'll give them to us.

This professor is one of the best I have had. This is the second time I have taken his class and would willingly take his class again. He is very kind and cares about his students. He is accessible outside of class and makes sure we have plenty of resources to help us succeed in the course.

Professor Casselman is an amazing professor. He has been so accommodating during COVID-19 and genuinely cares about his students. He goes above and beyond to make sure his students are successful. Would 100% recommend to all students to take him for OCHEM!!!

This man is a gift from god. He's a relatable person who understands the worries students have. While the homework assignments are hard as hell, I actually feel like I'm getting something out of the class each time we meet. Without a doubt, Casselman is the only professor to take for organic chemistry.

Professor Casselman is one of the best in UCR. Ochem in general is difficult and he does a good job in his lecture notes and explanation. Your final grade is honestly based on how much you really studied and practiced ultimately. Very considerate of personal conflicts and have accommodated his exam and class for his students. Had him for OCHEM 8ABC

I'm not sure what these people are talking about him retracting the accommodations he made for the final. The original final was going to be in class and proctored, and he switched it to an open note take home final that we had a whole week to do. Sometimes he gets a little snippy, I agree, but he's a great instructor.

Had him for 8A and 8C in the summer and he genuinely wants his students to pass and actually learn the material. You do gotta study outside of lecture and assignments and go to lecture because clickers really do help your grade at the end of the quarter!

For his summer online class of chem008c, he made homework make up most of the grade of the class. He allowed people to collaborate on the homework. His final reflected on the homework and lecture notes. His lecture notes are clear and straight to the point. Overall, he was an amazing prof. DONT USE CHEGG OR ELSE THERE WILL BE REPRECUSSIONS.

Okay you might be seeing my grade and wondering why I gave him such a good rating. Well I was going through stuff during it so I ended with a C- BUT Casselman had some of the best office hours I've been to and he was extremely likable. He explained clearly with examples in lecture and if you give this course some effort, I can see an A being easy.

My advice for getting an A in this class is to read up on the chapters before lecture and then everything he says will make sense. Homework and quizzes were open note, so it was pretty easy to get a 100 on those. If you can breeze through the homework and quizzes then the final will be easy for you since they're practically on the same level.

I definitely would recommend this professor. He did the best as he could to make the fall quarter for CHEM008A as accessible and manageable considering all the difficulties that came with the pandemic. All his lectures are recorded and homework is collaborative. You would have to try really hard to fail because homework is already 65% of your grade

The class itself is tough. That being said Casselman is a great professor who actually tries to teach his students. Ask questions, DO YOUR HOMEWOK, attend classes and you will be fine.

This is the best experience I've had with a professor online. 65% of the grade was homework and quizzes which you had a few days to over a week to do and you could collaborate on. Then the final was open note and I felt was very reflective of the homework and example problem we had. Definetly go to SI session and make sure to pratice

Most of our grade was based on homework, quizzes, and class activity. I was able to get full points in the quiz and class activities and I got 223/250 on the hw. the only test he had was a final, and he did 3 review sessions that were similar to the final. As long as you attend, do the hw, read and practice you can pass the class with C or higher

I am just glad I didn't fail. We didn't take midterms we only took a final. There were assignments and quizzes that you could work with other students to get done. There was no extra credit. He is a nice man.

I would definitely take Casselman's class again. He is super clear when teaching all of the topics and his course is very organized. Homework was a big portion of the grade and replaced having midterms. Final is weighed heavily but doable because he provided a lot of resources. To do well in this class, go to every single SI session.

If you spend a little bit of time learning his slides and their concepts, you will at least get a B- (the class average). I could have gotten an A, but I started off very lazy. Reading the book is useless; if you have a basic understanding of his slides. If I could redo the class, I would exclusively use his slides and all the practice problems.

By no means was his class easy, but it wasn't impossible. Roughly 85% of the class grade is the midterms and final. Focus on lectures. Book is useless for the most part. Most of his exam problems come from his slides. The guy may be a smart a**, but he knows organic chemistry very well. Pay attention, and you'll do well. Wouldn't recommend skipping

You will need to study a lot but the lectures and practice problems Casselmam provides are super helpful. He hosted many office hours and review sessions and he definitely cares about students that are willing to learn. Getting a decent grade is easy if you actually put in the work and use all the resources he provides you with. Avoid cramming

I really liked his class and he explained concepts really well! The exams were pretty fair since the questions were really similar to the poll questions. The questions are tricky but they really make you understand the concepts he teaches in class. If you do the practice problems in the textbook, it will be good practice for the exams questions.

Casselman's teaching style is very easy to follow and I can honestly say that his exams are doable if you actually spend the time to try and understand the material. He records lectures, is very understanding of any unprecedented circumstances that may arise, is very accessible, and helpful during office hours. Grades determined by adjusted scale.

It's Ochem so its def touch. But his lectures are really good and easy to follow. Has self assessments most weeks so you can test yourself on content learned in the week. Tests are touch, it is ochem, but they're doable. I would say he's approachable during his office hours and seems to want to help students.

Amazing chem proffessor. Coming from someone who hates chem with a passion he made it bearable. Lots of extra credit opporunities. Test heavy but they were all fair tests on stuff we went over in class. Definetely take advantage of self assessments and activities. Long as you do the practice problems and dont cram last minute you should be fine.

It's hard not to like Casselman. His lectures are easy to follow, and he is pretty organized. His tests are very fair, no surprises on what will be there, but he wants to you to know it all well. His class isn't curved, but the scale is 85/70/55 A/B/C, which is fair. 15% of free points for participation. Over 5% of extra credit too.

After failing CHEM008A the first time around I wasn't too excited to take this class again. However, Dr. Casselman makes things SO EASY. Compared to Hooley I would say that Casselman is 100x easier and way more understanding. For the first time I would say that Chemistry is actually fun AND interesting.

Casselman is the best of all ochem faculty, his exams are extremely understandable with a fair grade scale. Don't expect a curve as he already lowered grading scales is extremely easy to get a B but if you want an A you must work very hard. This class tests your self-motivation to learn and not fall behind otherwise you will be lost forever

Amazing professor. Organized and easy to follow. Practice problems are given as self-assessments and in-class activities. ATTEND CLASS!! His exams are easy to understand. I took him for 8A and also got an A. Attending lectures isn't enough you get what you put in. Extremely fair grading scale.

Great professor! Honestly as long as you put in the work and try to understand lecture materials on a deeper level, you'll do great. I took him and got an A in 8A; honestly SI session helps a ton. His midterms are straightforward and he does not test on things he hasn't covered. Extra credit is offered on the final and can save your grade!

Had Casselman for 8C, easy overall. A lot less material than 8A/8B, just more advanced. Gave 40 points of extra credit out of 400. If you put in the work, you pass and do well. If you think you deserve a curved passing grade, then you're probably going to fail.

Casselman is the GOAT. Lectures are easy to follow, pretty funny in a sarcastic way. Lots of exam points, but homework is graded for participation only. Wants you to know the material so you can do well in 8B. You need to score well on exams, you won't pass with 30% averages like those who have Hooley.

It's ochem, it's hard. It's none of them profs are easy. Casselman makes it at least okay. There's a lot of reactions in 8B and it can get rushed, but that's because he takes the time to explain everything so you can understand it. Tests are a mix of MC and FR. Curves a little, but expects you to know most of it for a good grade.

Casselman wants you to really learn the material, so he doesn't curve like Hooley does. Casselman's exam questions are super direct, nothing tricky. Do the self assessments, the practice tests, the book problems, the class worksheets. It's not easy, but it's ochem, it's always hard, but he makes it a lot easier than others do.

AWESOME PROFESSOR! Tests match his practices and he provides lost of it. I did not go to any office hours and did not touch the textbook and did well. Just PAY ATTENTION in lecture, ask questions on slack if you have them, REWATCH lectures/retake notes (Organize everything in a way that makes sense to you), practice over and over and you'll get it

Excellent Professor. The man literally does research on teaching chemistry, so he's a rare exception where a professor prioritizing their research actually benefits you.Various resources given, including yuja videos, extra credit, office hours, and a slack where he responds to any questions asked (sometimes the night before). Ultimately, his goal i

Casselman is polarizing. He teaches well and wants you to know the material. He is going to make you work for it though. If you're hoping to get by with a fat curve, take anybody else. But if you're putting in the work, he's awesome.

you will learn ochem with him. most of the people that don't do well just don't know how to study. he gives you every resource possible to excel in his class. he has no explicit curve but the grading scale + extra credit basically gives you about 8-10%. its ochem, itll be hard, so expect to struggle and learn

Pro Tip: Do the Organic Chem as the Second Language Book up until alkyne and addition reactions and you will get at least an A-. Fair professor but some topics will require you to watch his short video lectures. I also recommend going to SI as well! Extra credit on the final can bring your grade up a lot depending on how well you do.

Organic Chemistry, the major killer. Haha I don't know it wasn't bad and I think Casselman is cool but I found myself getting lost with trying to study too much and learn too many things at the end. Next time for CHEM008B I'm going to try to make sure to keep it simple and stick with what is being taught and don't ask why and just memorize.

Hard but not too hard class. It's super clear how to get a good grade in his class. Tests are exactly what is taught. not sure why ppl say that his tests aren't fair, all the same content from lecture and the problems come from the homework. Homework isn't graded, but worth 15% of ur grade. Clickers are extra credit, 20 pts of EC from final too.

Casselman is a fun prof. Lectures are interesting and easy to follow, not a lot of things that are extra and not tested. Office hours are low key helpful, he's good for advise about grad school and life too. Or just talk about anime

Recorded lectures. Do not cram OChem. Practice exams reflect what is expected on the exam. Textbook problems are overcomplicated. 80% participation in PollEvs for 4 pts e.c. 50% for 2 pts. Refund policy on final: Do good on MT1, MT2 material on final for extra pts. Grading: - MT1 80pts - MT2 80 pts - Final 180 pts* - Self assessments 60 pts. -Q

Casselman makes 8B doable. Lots of NMR at the beginning, but he makes it fun and a puzzle. The rest of it is tons of mechanisms, but he tells us what is most important to know for exams. Also does a great job of explaining why things happen, not just telling us what happens. Lots of practice problems. tons of extra credit.

Goat. He gave almost 40 point of extra credit for just a 400 point class. and 60 points for just turning in the homework. Anybody who complains about Casselman being hard isn't trying. That final? literally everything from worksheets and homework. Super fair. Lectures are good, and activities are super helpful.

ngl he is the easiest ochem prof at ucr, if you are complaining about his difficulty then you're doomed for future premed classes

I feel confident in what I have learned in this class and feel good about the grade I earned. I am extremely thankful I had the opportunity to have Casselman as my professor. He doesn't need to hold office hours or give all the information needed on the test. All you need is true effort to see yourself succeed! Understand don't memorize!! :)

This is my second time having Casselman. His class is not easy but if you put in the work it's very doable I would take him again. Watching YouTube for me helped a lot since I don't just like relying on lecture notes. Making notecards is a must. Find a study habit I had him 8A got a C-(barley passed) and this time I got a B with better test scores.

He is very fair and gives you everything you need ti know for exams. Not an easy A but a doable one. He really cares about teaching and tries his best to give as many A's as possible.

He's good, easy to get a good grade with work. More work than you think but it's not terrible. Exams are mostly worksheet and homework problems ina different form. Practice lots and you'll be fine!

Casselman is great but be prepared to have to study outside of class heavily. His lecture slides are helpful with learning the material but to pass the class you need to learn how to apply the different mechanisms and reactions. Reaction maps are helpful and find YouTube videos with practice problems and you'll do fine.

Best organic chemistry professor. He is caring, supportive, clear and hot. His test though are otherwise difficult. Weekly homework assignments is helpful for this. Other than that, he is one of the best professors I had at UCR.

Casselman makes this class doable with his clear explanations and tons of practice problems. Unstuck ai was a great supplementary tool for me. Definitely put in the work, but it's very manageable.

four words. GREATEST OF ALL TIME. literally the MJ of organic chemistry. its up to you to do the work. his tests are very easy, you just have to know your stuff 100% and ask him for help if you do not.

He's a great professor and his lectures were SUPER clear, but be ready to practice a bunch and do some self learning because he only really teaches you the basics/what you need to know. The way he grades his tests were probably my least favorite part about taking the course, but as a professor he's really good. His tests again were just horrific.

AMAZING professor! def the best choice for chem008a. His tests are very fair and doable however his grading policy is a bit harsh. But honestly, he's very kind and approachable and really wants his students to do well.

The class is really hard, but he is an AWESOME PROFESSOR. I think the exams though can be pretty hard, you really need to study ahead and beyond the lectures to pass. There is an assignment every week which helps. but go to SI. Also more improtnaly he's CUTE

Class grade is based upon 2 Midterms (35%), Non-graded worksheets (20%), and a final (45%). EC offered (about 8%) boost. Exams are a mixture of MCQ/FCQ; not difficult, they are just tedious because Casselman looks for minute details in explanation and specific drawings. Going to SI or having a past exam is literally the only way of getting an A.

I LOVE Casselman! He is such a well thought out and thorough professor for his course material and ensures that we have no problem with the content. His exams are representative of what is taught during lectures as well as the homework assignments provided. He wants students to understand orgo vs memorize. Go to SI, helps alot. 10/10 Would Rec.

not sure why others complain about his tests, most of the questions are just repeated homework and worksheet problems. He has standards, but they are very reasonable. lectures are easy to digest and he's very open to questions. go to office hours! he teaches you how to solve problems there, otherwise you're on your own

LOVE CASSELMAN! I would say though that his exams are very similar to the optional homeworks he gives you. People fall quarter did get an advantage during their exam with the fire alarm, ruining the curve. overall he is nice

Casselman's lectures are straight-forward and very helpful. Self assessments and any videos posted on Canvas are super helpful so take advantage of the materials he provides!! Tests are very reasonable, never had any content that was not learned. Only complaint is that he crammed reactions before the 2nd midterm. Be prepared to study a lot.

Professor Casselman cares about the success and understanding of his students. Come to lecture and be proactive. He moves at a fast pace and gives good examples in class. Be sure to stay on top of work and the self study material. Very test heavy. Be sure to understand the material, not just memorize it. Good luck guys!

Two years on, I can say he is one of the best instructors I've had. He clearly explained the grading and exam format. Attending his office hours when in doubt is key, and extra help is invaluable. USE OCHEM as a second language to succeed; the exams, though tough, mirror his lessons. The class structure will help you even outside of his class.

He teaches better than the other professor and he explains certain concepts thoroughly but he rushes the content at times because he didn't have enough time and he won't be clear about certain things he will grade on. Overall, a good teacher but isn't the most organized. I had to do quite a bit of studying on my own.

Casselman lectures are packed with info, but yeah, it's just the basics. Part of the class is learning what to do with those basics. He gives lots of practice problems so there's no excuse not knowing what's on the exams. Keys to success: 1) show up, 2) practice. If you coasted through gen chem with no work, you will struggle with ochem.

Records lectures, and puts slides up in Drive. Make sure to attend class on days with the practice papers. Very similar to what he has on the midterm. Rushes in the last half. Throws a ton of reactions at you. You have to study on your own.

Chill teacher, while the class was difficult I feel like he made things pretty easy to understand.

very good professor. be sure to go lectures, especially when there's an activity and work with peers, it helps a lot. there was definitely some self study that had to be done, but u should lwk be doing that anyways, has a lot of resources practice problems, self assessments, practice exams etc. just stay on top of things and attend SI and ur good

Honestly I could have achieved a higher grade if I didn't try to rush all my studying for the weekend and then the exam would be on Monday. Guys a decent teacher but I think if you pair yourself with the "O Chem As A Second Language" book, you are in really good shape to get an A, no doubt.

Amazing supportive professor, provides lots of supplemental instruction to learn, study, practice etc. Material is fairly difficult but with practice a lot can be memorized/understood especially with the practice he gives. Tests are a fair reflection of what is taught. Genuine professor that tries to help his students. 10/10 class (tough material).

Casselman is a good professor. It's just that his tests are extremely hard, and he grades even harder. 80% of your grade will fall on the exams, and 20% will fall on HW (graded by completion). He doesn't curve. He does give some EC but not much. Honestly, the best tool you have is gonna be the OCHEM tutor and studying your old midterms. Good luck.

structure of the class + lectures make it easy to understand the material and get an A, but you definitely have to want it or neither will be possible. leaving this a year after taking 8a/b with dr casselman; don't be afraid to ask him for help, he is an understanding guy. and do the practice exams!

Casselman is an amazing lecturer and is the best professor to learn ochem from. He does practice problems in class and is very helpful during office hours. I explains things in an easy way to understand, and his tests are fair and things you have seen in class. I am taking 8C with him over the summer.

Best O Chem prof. Great lectures, and all assignments helped me learn better. Tests are very hard, go to OH if you have any gaps in learning. I still remember all he taught because he cares about student learning. HW is graded as complete, poll ev in class.

Reasonable professor who teaches a lot of very important concepts. What Casselman taught in his class and focused on is the present in the core of many other upper-division classes. Obviously it's a challenging class but Casselman did a really good job setting me up for success and a better level of understanding in many of my other classes.

The bad reviews are from people who didn't study. The class is time-consuming, but Casselman offers numerous resources, including lots of practice problems and lots of office hours. stay on top of weekly self-assessments (these reflect the exam problems). He does not curve, but 85% is an A. Casselman is a great lecturer and a good person overall.

Ochem is difficult, he's one of the better professors who teaches Ochem but don't expect to get a good grade without studying. From week 1 you should do one or all of these three things: office hours, si, ochem as a second language. You aren't tested on the exceptions which is good. Know your material and understand how to apply it in the exam.

Best professor for 008A, but doesn't curve. Concepts build up over the quarter, but aren't difficult if you study. Midterms have many questions so you have to know the content well. Did bad on midterms (61%, 50%) but locked in and got a 90% on the final. Ending with a A- with EC(~14pts) and redemption points(max 20pts)

The absolute goat.

The best prof you can get for ochem. Attend office hours consistently and do ochem as a second language. A couple days before the midterm, spam practice problems and you'll be set. All exams are fair content wise. It's really hard to finish the midterms in 50 min lwk unfair but final makes up for that as plenty of time is provided. effort = A

This is one of the BEST professors you can have for ochem! There was a total of 34 extra credit points, and the tests were completely fair. Casselman also has amazing lectures, and if you supplement his teaching with Ochem as a second language, you will do great!

i wish i could marry him

Great professor, really good lectures, and gives ample extra credit at the end of the course. Definitely take if you want to learn and set yourself up for ochem b and c. Put in the work and it is an easy A.
