Homework 6 is available. It is due March 12, with no late submissions allowed. It was simplified shortly just after release, so make sure you have version 1.76 2021/03/04 00:26:40 or later (see the bottom of the homework for the version number).

The project's due date has been delayed until March 8.
A typo in Homework 5 has been fixed by changing (define test-expr-x '(+ 3 ((lambda (a b) (list a b)) 1 2))) to (define test-expr-x '(apply + 3 ((lambda (a b) (list a b)) 1 2))), and similarly for test-expr-y. Also, the assignment has been clarified to say that expr-compare should not worry about exceptions in expressions, and that test-expr-compare can assume that neither argument raises an exception when evaluated. (Thanks to Sara Liang for pointing out these problems in the assignment.)

Here are suggestions if you're interested in the course but are neither enrolled nor on the waiting list.
- Read Enrollment in Undergraduate Computer Science Classes and follow its advice.
- Any PTEs are not typically given out until the end of the second week, to make sure that enough resources are available. You can try coming to classes before then. Sign up on any attendance sheet that is being passed around.
