Hi all. I just got the acceptence letter from Purdue University. I got A on all my senior year courses so far except AP Calculus AB. I got B in the first quarter, D in the second quarter, and a D as the first semester grade. I am going to major in Philosophy which is kind of unrelated to Math. I have already completed three years of Math which is required for graduation. So would failing AP Calculus AB cause Purdue University to cancel my acceptance? My Calculus teacher is a really harsh person, it is impossible for him to be kind and curve my scores. I tried really hard on Math but I just cannot understand some concepts.
