Umich Econ VS USC Marshall Business

@SeattleTW I think I’m going to go to Michigan! I’ve really wanted to go there but I was trying to convince myself otherwise but that’s where I want to go. If I do well in Econ at Michigan, what do you think my chances are of getting into Marshall at USC for my MBA? I know this sounds silly but I am afraid I won’t get accepted in the future if I withdraw my application from USC for undergrad.
