cherry - i'll be sure to post if/when i found out. i was on the phone with both bank of america and citibank last night, and i forgot to ask this question. by the time i remembered, their customer service line was closed for the night.
jeffjoe - i think you're right that it's monthly, but i just need to confirm. you're also right about these loans being great for the banks - they wouldn't do it if they didn't make money off of it. unfortunately, i have no other route to go, because working during the school year is, plain and simple, not an option for me. i guess the best thing i can do is work to pay them off as quickly as possible, so as to give the bank as little extra money as possible...
