Is taking Calculus AB and AP Stats Senior Year too weak for schools like Wharton?

Happy to help! Some schools have you fill out what is known as a brag sheet so they can learn more about you or some sort of questionnaire, other schools will have appointments with you to discuss your college progress at which point you can mention this. Don’t pester them about it though: they fill out so many academic reports they have probably gotten the hang of it and understand what to mention and what not to.
