Dropping AP Calculus from High School Senior year- Will this affect my College Admission?

There is no lower level Calc offered by my school. So far got into NSU, CWRU, KU, and couple colleges in MI.

Bummer there is no lower level calc than AP.

Not sure what NSU is, but you will need to tell all of these schools that you are dropping calc before you do so. Perhaps that could get your counselor to wait? The schools you were accepted to will want to give their approval for any senior year course changes. How is it that you have already heard an admissions decision from CWRU?
