> Do you think you’re going to learn calculus better than you would at flagship state U?

Yes. Compare this Harvard Calc I final [0] to that of UNC Charlotte [1]. The test format of the Harvard exam works in the student's favor, but the questions are more difficult, more conceptual, and encompass optional topics that are not in a typical Calc I course (PDFs, Midi function). The Harvard class also requires students to demonstrate competency in various proofs that would not be required in a purely computational Calc I class.
