Berkeley vs USC (Help fast; deadline in one week)

What would your backup plans be if:

A. You go to UCB and later do not get into the business major and do not get admitted as a transfer to USC? Would you do some other major at UCB, or also have transfer applications to other schools?

B. You go to a community college and do not get admitted to either USC or UCB. What other schools would you apply to transfer to that you would be satisfied attending?
