is that the promissory note?
if so:
you should have gotten a 2 page letter in the mail just before the book list was sent out. the first page was from the lender. the second page was from bc. the whole thing just tells you to go to some website and fill out a bunch of forms and check some boxes. i think they were sent to our perm addresses. once you are done entering in all the crap on the website, you can download a .pdf of your promissory note.
id call bc financial aid on monday if you havent gotten the letter (assuming that you are even talking about the promissory note thing).
also, you will need to have your federal PIN (the same one that you used to e-sign the FAFSA). so if you dont have it, or forgot it (like i did), log into the FAFSA website tonight and request the PIN now as it does take a few days to process.
