I plan on paying out of pocket this coming fall semester at a hometown community college. I have already applied and been accepted. I was placed on financial aid probation from my 1st semester at a different community college and acknowledge that I've lost financial aid.
Unless you'd like having those F's on your permanent record, definitely drop your classes. However, from my experience there is a time period in which one can still withdraw from the course so double check that you have not passed it already. As for the other question, I don't know.
