BROCK!!!!!
Mr. Brock is not only a teacher, but he's a cool teacher. He's not one of those teachers who doesn't bond with their kids. He's a genuine and awesome person. You'd be lucky to have him as a teacher. He is always being sarcastic so don't take it seriously. He has an awesome and a fun way of remembering things that you need to know for the exam. So the bottom line is that you need to listen to Brock to get a 5 on the AP exam. He's the greatest teacher of all time.
