Nap, did you ever decide on a major? Are you currently at a 4 yr institution? How did this past semester go?
You’ve now exhausted all 12 terms of Pell Grant, without obtaining a 4 year degree. I’m assuming that you are eligible for a federal loan of $7500/yr for the next year, possibly two, considering that you are at junior at the 4 yr institution that I assume you’ve transferred to. Private loans would be more expensive than the federal loans. Perhaps your best option would be to work part time and go to school part time, using the federal loan, until you’ve maxed that out.
I would suggest that you make an appointment with the financial aid office at the 4 yr institution which you are attending, and ask them for help figuring out options. You should seriously consider how you’re going to obtain a marketable degree or skill with your future schooling, so that you won’t have to default on the loans.
