The remainder of my financial aid that was not used to pay tuition was placed as a credit with the school. This money was not refunded to me and was only available through the school. I purchased my books through the school's online store with the credits I had but I'm wondering sense the books were potentially available from other retailers if they would still qualify as educational material required to be purchased from the school or if they should be listed as educational material not required to be purchased from the school. To my knowledge I did not have access to this money other than going through the school store and using the credits I had.
