For one unit, there’s always a PE class.I’d suggest you take something academic though. perhaps a GE course. You want to stay on pace to graduate and give yourself some leeway in case something goes wrong.
I’d suggest you steer clear of private loans altogether. The terms are pretty onerous and the debt will hang with you a LONG time… Not sure how short you are but,if a part time job won’t fill the gap, you really can’t afford the .school. You may want to start at a CC, save some money, then transfer in.
Good luck
