I am taking HL math next year as a rising senior in the IB Program. Last year I took AP Calc AB and got a 5, and I also took business calculus at my local community college. Speaking to a Wharton admissions officer she stressed the importance of Calc. So I am signed up to take Calc 2 at my local college along with HL Math. But what exactly does HL math cover and is their any other classes that will better supplement my application.
