My top 3 schools are Cornell, Dartmouth and Brown. And up to this point I've had a 4.0, but in AP Physics 1 I think I'm only going to be able to pull off a B+. Only one person last year got an A in this class and its really difficult. By senior year I will have taken 8 APs: AP Biology, AP US History, AP World History, AP Physics 1, AP English Lit, AP Calc BC, AP English Lang, and AP Psychology. My entire courseload is either honors, AP or dual enrollment. I got a 1510 on my SAT. Will a B+ in my Junior year absolutely kill my shot at these 3 schools? My cumulative UW GPA would drop to a 3.98.
