If you get any finaid, they will apply it to your BARC account. So if you're given $a in whatever finaid, and you owe $b because of x, y, and z fees, they will $(b-a) = $c where c can be a positive or negative number. Depending on c, you will either have to pay more or you will get a check for c value.
Gold and Blue Opp Plan doesn't "cover" books. It'll just pay how ever much you're given. Then if you over paid BARC, you get a check and theoretically, you can use that check to help pay for books.
