I did not write the September LSAT, but this is what I plan to do after the December LSAT:

Hangout with family and/or friends! Do everything you couldn't do because you were chained to your desk while preparing for the exam.

Exercise! Exercise is my favorite way of getting any nonsense off my mind. Bonus, it's good for you, mentally and physically.

Try to learn a new language or skill! There are lots of free online resources for learning a new language. I plan on using Coursera.

Goodluck, I'm sure you killed the LSAT!

@ thank you!

I'm hitting the 1100+ mark now, and I don't think that's enough time for my target score. So much to learn, and the more you learn, the less you know for sure. Give yourself ample time!
