Chances of getting into Wharton undergrad at the University of Pennsylvania?

I'd say it could happen, but it probably will not. Your SATs are a little low compared to the competition and by participating in all those after school activities could actually make you look like you spread yourself too thin, without really showing true pion in a handful of things. Also, the Ivys and especially there best programs (Ex. Wharton at Penn) are incredibly unpredictable. However, stranger things have happened. But don't count on it. However, there are plenty of other business schools may accept you. Look around College Confidential, could help you out.
