started the semester off diligently but then halfway through I went through two weeks where I didn't do jack shit and just drank and watched netflix. After that I yo-yo'd whether I kept up with work each week or not. I kept telling myself that I'd outline during thanksgiving with simply making median in class as my goal, but slacked off... is there possibly a way to avoid getting a C+ in contracts with only a day and a half for studying?

Hm, sounds like "Can I get all the benefits of working hard semester while not actually doing it?" NOPE. You might be able to avoid complete failure by studying a few (the most important) concepts and practicing applying them by writing today and tomorrow. Otherwise you're headed for a well-deserved poor grade. Sorry.
