Questions

How does Misc. extra credit work?

I apply it to either Academic or Peer, depending on which you have not yet maxed out.

What were the writeups for class 31 and 32?

I don't think there were any.

Does diet dew still taste good after eight bottles in two days?

I'm not sure it ever tasted good, but it certainly is no longer appealing.

Lab 1: Local Bindings

Writeup for Class 33: Exercise 4b
