Pulling a Jake

When you've got a big test or assignment due, but call in sick until you're certain that though at-home study you'll get a good mark. Pulling a Jake also includes telling all your friends that you did bad in a test, only to receive the highest grade possible at a later date.

James: Why isn't Tom at school today?
Bob: I think he's pulling a Jake.
James: Yeah probably, and I bet that when he turns up he'll tell us he that he failed the test.
