Wharton is one of the top business schools, if not THE top school in the nation. You need to have superior grades, be active in school clubs and teams, have done community service, and have tons of excellent references. Your entrance essay will be vital; just because it’s a business school, doesn’t mean you won’t need to be an excellent writer. The University of PA requires almost perfect scores. I notice you’ve made many errors in a short question; practice using capital letters. The University won’t accept “textspeak.” Get into the habit of writing correct English, even when you’re on a site like YA. Good luck. Study hard.

Get great grades. 3.8+ at a top college. Don’t worry too much about the major, take something that interests you: do not take all business classes.

Get involved with things other than schoolwork. Yes, you have to do both.
