Where to go to school? Please help!

Penn is my dream. Did not get in, I want to transfer next year for sophomore admission for CAS. I was accepted at UIUC and University of Toronto. Which of these should I go in order to go to Penn? UofT grades are deadly but its more prestigious. Im an international student. Please answer, both offers go until May 1!

Go to the school you like better and would be happy spending 4 years at. Chances of transferring to Penn are very slim.
