Only thing you can really do is to wait to hear back from them.
As far as FullSail being a very intensive program, yes- it is. Everyone I know that graduated from there was (for the most part) completley immersed in their job- er schooling. It's rough but if you're passionate about it you can get a lot out of it.
Also: Most colleges will want you to start paying back on loans when you graduate. This isn't a FullSail exclusive thing. In my case I have a six month grace period before my bills start coming due.
If you're going to be taking loans out- expect for them to want their money as soon as they can get it.
Make friends. Make games. Make money.
