Possible C in AP Calculus AB

Currently I have an 81.23 in ap calc ab and my final os tomorrow worth 20% of my grade. I have to get a 72 to pass with a B which is very unlikely. The teacher is extremely hard and everyone I’ve talked to for last year said the final isles the hardest test they’ve ever taken. I shooting for MIT, Georgia Tech, UC Berkeley. Wold a C kill my chances?

Given that many other applicants will be applying with As in AP Calc AB to MIT/UCB/G Tech, it will hurt your chances for sure. Since you’re looking at top STEM schools, I’m assuming you’re going into those fields, which means that it will hurt you even more- a very humanities-oriented kid might get away with a lower math grade (MIGHT).
