I had him for his first time teaching 101. It?s not remotely easy; the test looks nothing like the homework. His lectures are unbearable, trust me the people I sat around had no clue what he was talking about most of the time.

Dr. Folmer is a nice person, but he is almost too smart to teach. He expects you to remember everything that he says, the tests are NOTHING at all like the homework, the text book doesn't really help either. He makes chem 101 ridiculously hard. I would definitely not recommend him.

NEVER HAVE THIS PROFESSOR!!! He is horrible!!

Avoid this teacher unless you already know a lot about chemistry he is a nice person however teaches as though one already know exactly what he is talking about also he can be a little unapproachable also he does not respond to emails very fast if at all!

Whoever wrote that Jaap Folmer is nice and too smart to teach needs to get checked. Jaap Folmer is extremely arrogant and the fact that he cannot relay simple information simply is not a mark of brilliance. Teaching a 101 class is not that hard and he makes it extremely difficult. I would absolutely advise not taking him.

This teacher does not teach at the level of a freshman and he is extremely hard to understand. He randomly posts and moves homework and takes weeks to give you back your test grades. He looks down on you if you ask questions because you should "already know it." definitely do NOT recommend.

Didnt explain things well at all and assumed that you knew everything he was talking about in class. Moved to quickly with his power point in class and I was never able to take the notes needed to study. The only good thing about his class was the way he curved grades. He is the worst instructor ive ever had, through high school and through college

I emailed him numerous times throughout the semester asking questions about specific topics and he either would respond with smart comments or not respond at all. He is very rude and not a teacher that you will ever "get to know".

I'm not quite sure I can call Jaap an instructor. Everyone I talk to is having difficulty in his class. He expects us to know the material before he 'teaches' it to us, and we are required to do webassigns consistently not knowing what to do. No extra credit is offered and I do not believe he honestly cares how anyone does in the class.

Dr. Folmer is a terrible professor. DO NOT TAKE THIS CLASS. I got all A's in my high school chem course but might fail this class. Dr. Folmer does not explain anything, never responds to emails, and does nothing to help prepare his students for his impossible tests. I don't think he cares if his students fail which is why most of them do.

ABSOLUTELY the worst professor I've had. He does not care about his students which becomes apparent when he doesn't respond to any emails and his tests are on absolutely nothing we've discussed or that has been provided as study material. DON'T TAKE THIS CLASS. find another chemistry professor with a better rating and grade distribution.

HORRIBLE!!!! Impossible to learn from, the test have nothing to do with what he teaches and nothing on the tests comes from the homework. To pass the class you basically have to be a genius in chemistry beforehand.

Do not take chemistry with this teacher!!!!! awful!!! Worst teacher I have ever had! tests have nothing to do with anything he teaches you and he says he'll curve them but he doesn't. My classes average was a 73. I think maybe 2 people had an A and 5 with a B

He's awful. He doesn't respond to emails, his lectures aren't helpful, and have nothing to do with the tests nor the webassign... only the recitations which had different teachers were helpful. I still passed, but jesus, this class was awful. Would not recommend.

Let me give you a little bit of my background.. I graduated high school valedictorian of my class. I made ALL A's & B's first and second semester, EXCEPT for in Jaap's class. Homework assignments and class lectures were way more basic than exams. He admitted to asking exam questions in riddles. Worst learning experience EVER!

Jaap, although he may know his chemistry, cannot teach it at all. His lectures have no structure and only consist of him writing gibberish on the board. Nice man, but terrible teacher. Also, tests are very hard and rarely require calculation. They are all theory-based questions.

DO NOT TAKE WITH FOLMER! absolutely terrible at explaining. Goes off on random tangents and told my class 20% of us needed to cut our losses and go flip burgers since we didnt do well on the test. His tests are puzzles and even though he curves 20 points, averages were in the 60s. TAKE WITH ANYONE ELSE BUT HIM

He doesn't take attendance, so most of the class never came. It's understandable though, because even if you pay 100% attention, you still won't understand anything. The tests are nearly impossible because he words the questions weirdly. TAKE ANY OTHER PROFESSOR BUT FOLMER.

AT ALL COSTS DO NOT TAKE FOLMER. Seriously wait another semester or literally take any other professor. I wish that I had never taken him. Granted I passed the class, but it was not easy. His tests are impossible and he does not care about his students. He is rude and is the worst teacher I have ever had. AVOID FOLMER

probably a nice guy but my goodness how gave him a teaching license.

I would not recommend this professor for a student who needs to take classes past Ch101. If you need to take Organic Chemistry of Intro. to Organic, I definitely suggest taking another teacher. I passed, and got B's on my exams. But I owe that ALL to my tutor. Folmer gives you and extra 25% on your exams, but even with that, you don't do well.

Avoid him if you can. His tests are hard and long. The first 3 tests were too long and complex for the 50 minutes allowed, but the final was ok time-wise. He doesn't have a plan for his lectures. Starts talking about something and ends up talking about something else. If you must take him practice his old tests and use flashcards for memorization.

WORST PROF EVER!! Whatever you do, do not take him... literally anyone else. Rants in class about things off topic, homework NOTHING like the test, rude to students, accent hard to understand etc..

Dr. Folmer is a bad teacher. He spends half of the time tell you that the stuff on his slides is actually "not true," and that there are always little exceptions, making it difficult to know what to take notes on. He "talks" about chemistry - almost in a theoretical sense - rather than actually just teaching the course. This is science, not english

Dr. Folmer is very smart, but seems to advanced to teach 101. His lectures are confusing and his tests are very difficult compared to the level of information lectured. Must read textbook. Not helpful outside of class and very seldom responds to e-mails. Would not recommend no matter what.

Horrible

Extremely difficult class for First Year students. Strongly advise against taking the class.

Oh Jaap. He will tell you his life story over and over again. During his lectures, he doesn't really say anything information wise. I have learned next to nothing going to the lectures. SO GET READY TO READ A HUGE CHEM BOOK. His tests are awful! Its not a simple answer this problem like a normal chem teacher, its like 5 questions in one. DONT DO IT

Jaap Folmer is a horrible teacher. I took 3 full years of chemistry in high school, and expected to get into CH101 and do perfectly well. I'm doing ok, but not learning a thing! all he does is give crazy, ridiculous tests and curve them by like 30 points. What he tries to teach in class isn't on the homeworks or on the test, do not take his class!

Jaap Folmer is an awesome professor personally, but thats basically the extent of it. His lectures are very confusing, they are not taught in a chronological order material-wise, and it is very clear he is simply 'winging it'. His tests are also very abstract. And just for perspective, the class average on the last test was a 48%...

1. Cargo shorts 2. Run away 3. All done here

My advice to you is: read the following rates (they aren't lying). Folmer is difficult to understand and hardly explains chemistry topics where it makes any sense!! I was advised not to take him, but thought maybe I would just have to work harder. Unless you have a serious chemistry foundation or are a genius, do not take his class.

Tests are extremely difficult, the book and his notes/powerpoint are no help. Horrible professor, doesn't lecture on things relevant to the class topic and doesn't help when you stop by office hours. Completely disrespectful no matter how polite you are to him.

Tests are impossible and his lectures are difficult to understand. Highly recommend not taking his class

I would not recommend taking his class. Lectures don't help you learn, tests are impossible and he doesn't give you back your tests, only the grade. Overall would not recommend him to anyone.

He is clearly knowledgeable about his field of study, yet lack the ability to convey this knowledge to his students. The lectures are quite sporadic and random without any solid goal. Highly recommend reading the book before class.

His lectures are not similar to the tests, but he will mention random facts and they have a good chance to be on the test. His class is way too advanced for an introductory chem that most people have to take, even if your major has nothing to do with chem. At all costs, take it with someone else.

I knew more Chemistry before taking this class.

HIs teaching style can only be described as supplemental to the book. He seems to understand the subject very well however he thinks that he is teaching to a group of seniors. He wont go over the basics but will instead jump straight to the complex concepts. Tests are the worst part, extremely hard and not related to class material.

Folmer does not teach well, and makes simple concepts way too complex. His tests are just made to trick you, and it is hit or miss even if you know the information well. His grade averages are so bad that he has to have set curves before he gives tests. Although the curves can boost your grade quite a bit, I would not recommend taking this class.

the worst 101 professor out there. i stopped going to class after the first test and read the book and ended up making higher grades on the tests. the tests are full of trick questions that are impossible to logically think through in the time for the test.

my friend didn't go to class all semester and got a higher grade than me. avoid this class if you can. if you can't, read the textbook and pray.

One of the rudest professors I have ever encountered. Threatened to have anyone who missed class more than three times reported to the university for admittance and financial aid reconsideration. When 50% of the class missed a so called "easy" test question, he said anyone who got it wrong should just give up school now and go flip burgers.
