I'm sure we're not the first to think of this, but here's how to make exam revision more successful by combining it with bondage.
Assuming there are two of you and you are boyfriend-girlfriend, take it in turns to tie each other spread-eagle to the bed. The captor sits straddling the captive's (topless is best) stomach facing their head and asks questions about the subject(s) being revised. Correct answers get a kiss and incorrect answers get a gentle twist of the nipple - this can be increased in severity if you are really into pain!
