Great professor. Incredibly knowledgeable about the course material and current events, so connected the two together in really interesting ways to teach fascinating facts. It was online so biweekly homework, twice weekly quick online quizzes, and a final group project. Not difficult and ample extra credit offered. He tried hard to accomodate.

By far the best professor I've ever had in the chemistry department. He's passionate about what he's teaching and very kind to his students. I took him for chem 150 and 123 and I wish he was teaching more courses because he's very knowledgeable. He's a very sweet, kind, and generous professor.

I had Professor De Vries for both CHEM 123 and CHEM 150. He is one of the most compassionate and flexible professors I've had, looking to ensure that students learn without having to worry about getting the grade they deserve. His lectures are very reflective of the exams and his weekly homework is never excessive, covering the topics adequately.

Professor De Vries is a good professor you just really have to put in the work to do well in the course. Every detail matters in lecture. He'll mentioned a very minute detail that you think won't matter and it'll end up on the exam. Exams are more than one answer apply so you really need to make sure you know the material. He's pretty forgiving tho

Not a bad professor, tried to make class entertaining, but Envirochem is pretty difficult to make interesting for me at least. Midterms were pretty hard. Each question had 5 answers, and you could choose one or more of the 5 choices, so you had to know literally everything. Also very inaccessible outside of class, hardly replies to emails.

It is extremely hard to stay focused. He speaks low, mumbles, and would go off on tangents which makes it very difficult to pay attention throughout the whole lecture. Posts slides online but they are practically useless without any context. Avoid him if you can.

Overall, professor Devries was a pretty good professor. His lectures were sometimes pretty boring (due to his monotone), but he would always try his best to be interactive with his students during the lectures. In terms of coursework, there are 3 midterms and a final ( all multiple choice). Get an A on the final, get an A in the class.

His lectures were very boring, I could not stay awake through most of them because his voice is low and he mumbles on random tangents. His tests were like playing a long game of trivia crack and everyone lost. Not a good test maker or lecturer. Nice guy though.

Took him at Yonsei International Summer School. He gives you a better grade if you show improvements throughout the course! Open note tests, good assignments. His lectures are a bit boring but he is a friendly person. Would take him again.

This class is very hard in the sense the material covered is not in the text book. Every chem major got C's on the tests. But Devries gives 60% of the class an A+ A or A-. That said if you are competent and put in some effort this class should be an easy A- and if you put in more effort a very easy A.

Adorable professor. Very sweet. Goes on tangents a lot, funny stories, TA writes midterm exams. Get an A on the final, get an A in the class. However the midterms are not as easy this quarter as they were in previous quarters. btw I HATE SAPLING.

De Vries is such a great professor. His sweater sets are always awesome as well! His tests focus on powerpoints but if you know this then his classes are a piece of cake. People who rate him harshly just never caught on I guess...

This class should have been interesting and relatively easy, but because De Vries just goes on long tangents about obscure things he fetishes about, environmental chemistry is more about trying to know what the TA will write on the exam, which does not correlate with the book or lectures well at all. He is a generous grade curver though.

Devries is a cool guy, but a bad professor. His tests are pretty easy, minus some of the completely random questions that are just based on facts in lecture. Going to lecture isn't the most helpful, so don't be too worried if you miss a few (but try to go as much as you can). Should be an easy A for most people though.

Really nice guy. Basically a chemistry version of Mr. Rogers. However, I found his lectures absolutely terrible. I couldn't pay attention at all due to his quiet voice, random tangents, and him quickly flipping through the slides. However, his tests are super easy so it makes up for it. Just go to CLAS and you'll get an A.

Awful as a chem professor, but his freshman seminar (the case against science) is pretty interesting. Mandatory attendance and presentations (but they're allowed to be bull). I didn't do two homework assignments and still got my P haha. It's decently interesting but it depends on who all is in your class and if they participate or not.

He's chill as a guy, but awful as a professor. He just goes on random tangents and then picks the randomest things to put on midterms/final. I'd go to class, goof off and talk with my friends, then go to CLAS and actually learn something. He also doesn't curve the class, be warned, but there's a ton of extra credit opportunities.

Easy A compared to other 1 series professors. If you actually want to learn take another professor. Such a slow lecturer

Very informative class, although the material is mostly based off on general chem courses(like a review) but later on you will get to learn diff chemical techniques in real life, he will go beyond the lecture material to stimulate your interest, is a very unique and fascinating guy, you should take his class.

He's a nice guy, the exams weren't easy for me, but my friends in the class all got B's without doing homework or attending class. I got a C+ doing all the HW & 100% attendance (~D average on my exams tho). I'd take him again.

Easiest class in the chem dept, google the old tests and you'll pass with flying colors. No reason not to take this class with De Vries. Never went to lecture and still got an A without the iclicker.

He has a very engaging teaching style (uses lots of demos and iClicker questions). Posts all of his ppt lectures online so you can be prepared for class. He is helpful with homework (answers e-mail quickly). Tests are fair and he goes over the exam key in class afterward. Great prof! Also quite cute and has the sweetest voice you'll ever hear.

Professor DeVries is awesome. His tests are very fair and he does not put trick questions on the exams. Come prepared to lecture having read the powerpoint a day before. Will help in understanding. Professor DeVries makes chemistry interesting and applicable to "everyday" life.

He seems like a very sweet old man, and that's what he is. A very sweet old man who will speak for 20 minutes and you might get one thing from that. You'll learn something, whether you learn a lot or not depends on if you read the book. I suggest trying to get someone else if you can.
