Comment:

Really nice professor and an expert in his field. Challenging course; make sure you come to class. Lectures are mostly very clear, but do make sure you understand details that might seem insignificant. Exams tended to be more similar to previous years' tests than to sample problems, but do practice, since the same questions won't be asked twice.

Comment:

Professor Crumbliss is hands down the best teacher I've had at Duke. He is clear, kind and even gave a disclaimer before the exam that he is not here to trick us. I can't say enough positive things. I'm so happy he teaches at Duke! Crumbles love

Comment:

Best science professor I've ever had. Tests what you know, not interested in what you don't know unlike many professors. He's so helpful and takes the time to make sure students really understand the material. Very practical. Take a class with him if you can!

good guy, really interested in chemistry, really wants his students to succeed. His lectures are much clearer and more interesting than palmers. Overall, he knows his stuff and does a good job of teaching to his students

Comment:

Not a hard class. Skip lecture, learn it on your own, do practice problems, and you should be fine. Can't comment on his teaching ability because I didn't wanna get up at 7 AM, but the tests really aren't bad as long as you start studying before midnight. The final was harder though, but had a nice curve I'd imagine.

Comment:

This class is kind of a pain; I felt like I was always doing work for chem between lab reports/homework/reading/prelabs/quizzes/studying, etc. however, they're not out to trick you; the material is (relatively) straightforward. If you study hard you will do well. Crumbliss' lectures are more important not to miss than Palmer's, in my opinion.

Comment:

Nice guy, really likes chemistry and it very clear when lecturing. Tests don't go along with what you've learned in lecture and the final was ridiculous... Be ready to apply the concepts to situations you don't even understand.

Comment:

His problems on the board are somewhat helpful and he's not really that bad, but i'd just recomend always reading the chapters in the book - lecture isn't nearly as important as that. If you do the homework problems then the tests aren't that bad at all.

Comment:

Crumbly!! He's really not very interesting at all and I can't tell you how many times I played poker or slept in his class. But presents the material really efficiently and in a way that is really easy to understand.

Comment:

I thought he was a great teacher. His lectures are very helpful and clear. He writes problems on the board a lot which is better than Palmer's powerpoints because they are easy to follow. He also repeats things lot to help you understand the main points. Definitely take his class

Comment:

This guy is the most boring guy ever. He never covers all the material he needs to in lecture and he repeats himself all the time. It is very frustrating. Palmer (who teaches the first half of this class) wasn't great, but he was much better than Crumbliss.

Comment:

Overall horrible teacher, hard/tricky tests, boring lectures (though he didn't use powerpoint like palmer, so it was a bit easier to stay awake). Wasn't so bad that I didn't go to class, but definitely made genchem one of the worst experiences of my undergraduate career. A bit less intimidating than Palmer, though.

Comment:

If you don't understand something in this class it's on you to figure it out. He never seems to complete everything he needs to cover in lecture and can come across as pompous. This isn't a class you want to take for kicks.

Comment:

For the most part follows the book. Maybe one question per test is not in the book. I thought he spent a little too much time doing examples on the board when similar/identical problems are in the textbook. Tests are good because they are as fair, though some found them tricky. Okay to skip lecture without missing too much

Comment:

Look up the chem professor "Palmer" to see what this guy is like (and physically they're practically twins). He uses the board rather than powerpoints, which can be rather sloppy and incomprehensible at times. You might need some caffeine to keep you awake in class, but he's not the WORST chem professor in the world.

Comment:

God awful. He's so boring in lecture, and if you have him at 8:45 am you'll either need crack or morphine to get through the painful seesion with him. Most people decided not to go to lecture he was so bad. His tests are also rediculous for no reason. Intro chem should not be painful like this.
