Post this same question in the transfer thread:

Also, USC wants to see your GEs and core classes knocked out when you come in as a transfer, you will see this confirmed by the many people posting on the transfer thread. You may also reach out to the transfer department and see if they will answer any of these questions, or get email of someone you can contact. Be prepared, it is one of the most competitive schools to get into anywhere.
