I’ve gotten a few emails from people who wanted to meet to discuss homework 7 before Tuesday’s class, which is great, of course—but the homework itself is not due until Thursday’s class. If you are having trouble getting started on homework 7, or are unsure of a few things, then:

• You are not alone.
• I can talk about them on Tuesday if you ask about them.

I think, in any event, I’ll probably try to work through one example tree in class, similar to the ones actually on homework 7.
