Genuinely sucks at teaching AP Stat. Harsh grading, unapproachable, and closed-minded. Thank God I regained my passion in stat in college. If you're interested in stat or want to take the AP exam, just buy a review book instead and sign up for the exam. The amount of stuff on the AP exam was covered in half a semester of college (pretty much a quarter in high school) course anyway.
Mr. Groose helped me whenever i had a problem, and i had alot of math-related problems throughout my freshman year
He didn't teach me anything, didn't ever answer questions, terrible teacher.
good teacher. helpful, little off topic but funny. easy to follow.
