He is an awful teacher and doesn't explain anything. He bullies kids and doesn't provide any help. Asked a girl in my class if she was dyslexic and made her cry. .01/10 rating he sucks

Doing well in Coller's AP Envi Sci class is very straightforward: Read the textbook and take notes in class, and you'll be fine. He's not lying, either. Students who do the work they're supposed to do will never fall behind. He's very knowledgeable and passionate about the subject he teaches; we learn far more than just the coursework in his class. Not the best lecturer, but he's still an excellent teacher.

Mr. Coller is a cool guy that actually cares about his students but his class is way too hard. His powerpoint notes don't help at all and he's unclear on the homework due. You use dropbox for all the class materials but he never checks up on it and most of the stuff isn't even in there.
