Transfer to USC as a sophomore
I'm an international student in a community college in north California (Diablo valley college), and I would like to transfer to USC, Miami U, U of Texas, or UPenn (but I think it will be impossible) next fall (13). My major is business and I'm pretty sure that I'll get all As this semester I'll plan to enroll a sport team and an honor club. How is it hard to transfer as a sophomore to these universities ? Or should I wait the junior year ? I will have more than 30 credits at the end of spring (like 16now+19 in spring).
