Yes, Mr. Brock is an alien... JK. Mr. Brock is a nice guy. He also has great taste in music! ;) He is a really helpful teacher. He is someone who is easy to get along with and he is an all around cool guy. I really enjoyed being in his class. He really is great at his job and knows how to prepare you for the AP exam, and that is coming from a lazy student who slacks off all the time. So if he can prepare someone like me for the AP exam, I have confidence in him that he can prepare you for the exam too! :)
