Yes, you will most likely end up fronting first semester tuition (7g or so). And as far as I know or have heard, loans won't come through until a few weeks into the first semester at least. So you'll need to support yourself for those weeks as well.
I have heard that if you are approved for a loan, Gardner is willing to work something out (or wait on your loan assuming it'll come in). But I don't know exactly how that works.
I ended up fronting my 7g through my credit card (Saba doesn't take credit either, so you'd have to pay yourself through PayPal or something and withdraw the cash) and saved up some cash for first semester. Hope that helps.
