Is There a Test to Do Proofs in 137?

If you were to talk to someone that was going into 137, what would be your best piece of advice for someone who's like never done proofs before? Well, I guess to make sure you watch all the videos. You should always try that. And take the opportunities given in class to work on something seriously. So they're not a test to see if you can do something right or not. They're supposed to help develop your understanding of something. It's absolutely okay if you don't get it and you're totally lost and you make lots of mistakes...that's what the instructor is there for.
