Has anyone here been accepted to Wharton RD, while taking AP calculus AB during their senior year?
as this is a Penn specific question, you should repost it on the Penn forum
http://www.admissions.upenn.edu/apply/whatpennlooksfor/hsprep says “a strong preparation in mathematics, particularly calculus”. The Penn MATH 104 that is the assumed to be the starting point in math for Wharton students is a typical second semester calculus course; high school calculus AB is assumed (those without or who did not do well enough take MATH 103, a typical first semester calculus course).
