I have had this professor twice (one for a seminar and one for chem 123), and he is so funny and caring. It is clear he prioritizes understanding and genuinely cares for his students. His lectures are useful, and his grading is fair. Honestly I would take him for a third time and recommend him to anyone.

The Case Against Science class was interesting but there was a lot less lecture than I was expecting. I was hoping he'd share his knowledge of the subject more but it was more group work and presentations. Fun class but do know that going into that

He's a really nice professor and his lectures are fun. He talks about topics like acid rains, global warming, how small stuff can affect our world in a great way. However, his exams don't make any sense. Take my advice and google his previous exams. Attendance is compulsory. Review the iClicker questions, and read all the lecture slides. Good luck!

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.
