I currently have AP Environmental, and I gotta say Mr. Gappy is a really cool teacher. I don't think any teacher can top him. I look forward to his class everyday as it is fun and exciting. Unlike many teachers, he is always in a good mood. I highly recommend switching to his class if you don't have him. His class schedule is also very smooth, so that you have much time to study for the upcoming tests. I hope I can meet professors like Mr. Gappy next year - Sultan Al-Azzawi

Mr.Gappy is a very cool teacher and an expert in medical biology. He writes the tests and the notes for them, so you will always be able to study for what is to be on the test. He is very fun and knowledgeable. I would definitely recommend him for any student wishing to take medical biology.

Gappy's funny, and he knows what he's talking about. If he ever calls you "doofus" or dirtbag" that means he likes you.
