I'll do anything for cake.
1) Accommodations is indeed usually used in the plural when you are talking about lodging, a hotel room, etc.
(An accomdation is when you change something to help someone be able to do something - like providing a sign-language interpreter for someone who is deaf.)
2) Often we use the singular form of a noun as an adjective. Table leg, piano bench, student ID card, etc. (There are a few execptions: sports arena, sports car)
3) I would use awarded. Or the credits will be conferred upon the student. Granted isn't quite right - and evaluated isn't even close.
