I think I figured out something to occupy me for the rest of the summer. I'm going to reteach myself electricity and magnetism for the advanced standing exam August 28th. I taught myself it in a month and a half last time, so this'll be easy; I have more free time (if I don't find a job) and I have two weeks more time. Unfortunately, the physics textbook I have doesn't cover all the topics, but I have my Barron's book and the Internet.
