If you're planning on majoring in math then a 5 on Calc BC shows nothing about whether you have learned calculus. You would want to take 18.014 and 18.024 at MIT, Calculus with Theory. If you can understand Apostol or Spivak and do the problems, then you don't need MIT's calculus classes.If I get a 5 on AP Calculus BC, do I still have to take Calculus II at MIT? Or I don't have to take it?
