jeff is SO awesome. his visuals make the material a lot easier to understand. he's laid back and totally understands where students are coming from. he's not big on attendance, but it helps a lot to go cause he'll focus on what'll be on tests. i think he's teaching 410 next sem, but anyone who gets him is really lucky. highly recommended!!

Professor Flowers really enjoys chemistry. During lecture, he has a tendency to go off on tangents and get ahead of himself. Labs are a waste of time, but if you ask him he gives you the answers. Tests are hard. Write down verbatim what he goes over in review, the questions are directly from the test. Extremely generous curve! pH: power of hydrogen

Flowers is a very frustrating teacher, especially if you are trying to do good in the class. He acts as if the material in his class is easy and therefore does a half-ass job when he teaches. Lectures get confusing, the book has helped me more than his teaching. He uses lab class for extra lecture time which gets boring... wouldn't reccommend him.

Flowers is a cool guy. He does know how to laugh and have a good time but when it came time to teach it kinda seemed like he didn't care. If you're looking to really learn chemistry I would take Prof Clay or Deline. Flowers just breezes through material just to get through it. I had to learn everything myself for the STANDARDIZED final he gave us.

Would take again

Flowers is awesome! My fav professor! He is so funny and engaging in class. He's so nice and helps. Class is math and test-heavy, but that's normal for chem. He pretty much tells you what's on tests in lecture and gives a cheat sheet packet. Study and you'll be good! I'm p sure anyone rating him bad is just mad because they didnt put enough effort.
