When I was in college, I majored in math and physics. Only two math classes gave me trouble. One was Real Analysis. There were just too many theorems. I couldn't remember them all, and then I couldn't figure out what to use to solve the problems on the test.

Eventually I realized that, out of maybe fifty theorems, only maybe three were used to prove all the others. So I memorized those three, and worked out anything else I needed for the test on the fly.

You don't need to keep up with the Hotness Of The Week(TM). You need to know the fundamentals well, and you need to be able to learn the rest when you need it.
