I concur with the previous review "Obviously intelligent guy, but he made me despise chemistry now. The class is very boring after the first marking period."

He's a good teacher but I think he sort of looks down a bit on students who don't understand as some of the other students.I think he misunderstands confusion in a student for a lack of trying. I don't think he means to though. He tries to help. He's a nice guy

Dr. Heffner is the epitome of a teacher. He makes sure to go over everything and has a well-defined agenda that students follow every class. He is very good at explaining concepts in detail and preparing handouts that reinforce material that he teaches. It is obvious that he knows what he is talking about. His class is the only class in which I am more than willing to do assigned homework. Really nice guy, too.

If every teacher were like Dr. Heffner, humanity would be 1000 years ahead of where it is today. His class can get a little boring, but his subtle sense of humor makes it a lot more enjoyable.

Really good teacher by making Chemistry fun and easy to understand. He breaks up his flat tone by sometimes having EXTREME BURSTS OF ENERGY out of nowhere, which is pretty amusing. He's pretty picky on short responses, but it is designed to help you understand the material completely. Just make sure to show your work and use correct sig figs!

His labs are super hard and his tests are tricky, but he is undoubtedly the best teacher I've ever had. You will leave his class with confidence in what you've learned and really prepares you for ap chem if you choose to take it.

He teaches all concepts and his worksheets should help you understand most of the class. His tests are easy if you studied for at least 2 hours (counting homework). He is a bit bad one-on-one but you should be good with the class overall (Chem)

Not sure about intro chem, but reg chem he speeds through so much material even when half the class is having trouble. He takes off points for such stupid and frustrating reasons on some tests but all labs, and is unwilling to help out on confusing labs. His class is extremely boring, also.

He was okay in intro to chem, but in regualr chem there's so much moreinfo and he does NOT teach it well. Also, he's lying when he tells your class he'll push back the quiz if the class is having trouble.
