A class where you realize you're stupid as fuck compared to everyone else. This is also one of the first classes where the grading is different compared to the usual US Grading System. It's college level intro class to mechanical physics, usually taken by Juniors and Seniors in High School but nobody really gives a fuck about that unless if you're some soulless college admission dude.
"Hey dude what science class are you taking this year?" - John
"I'm taking AP Physics C: Mechanics, I heard its easy" - Jerry
"W...Where'd you hear that from...?" - John
"Uh... some Sophomore that already took AP Calc BC" - Jerry (He's about to fucking fail)
