It’s also possible OP is no longer eligible for federal aid due to not meeting his school’s Satisfactory Academic Progress policy. There is a time-to-degree requirement in SAP policies, per federal regulations. Once the limit is reached, aid (including federal loans) stops.
If you plan to borrow private loans to complete your degree, you’ll need to do research online. Some schools have a preferred lender list, which might be a place to start.
If you are going to borrow private loans, it’s important to borrow as little as possible. I encourage you to meet with an academic advisor to create a plan that will get you to your degree with as few classes as possible. Fewer classes means lower tuition.
