The answers won’t be different now then they were in May. You can’t afford a $45k/year or more net cost on a $600 EFC. If you don’t pay the fall tuition bill you won’t be able to enroll. It doesn’t matter that a relative loaned you $400 to pay the deposit. All that does is confirm your intention to attend. When the fall bill comes due in August and it’s not paid a hold will be placed on the account and you won’t be permitted to register or attend classes. If you want to attend college this fall you really need to pick one that your family can afford.
