-One student session will be held every Wednesday from 3-4. The other will be arranged to fit the schedule of those who'd like to attend but can't make the Wednesday time. (We first proposed Tuesdays from 11-12, but this time turns out not to be so helpful.) If you're one of the students who wants to meet for Q&A at some other time in the week, let us know.

-There is now a [[lambda evaluator]] you can use in your browser (no need to install any software).
-It can help you check whether your answer to some of the homework questions works correctly.
-
-There is now a [library](/lambda_library) of lambda-calculus arithmetical and list operations, some relatively advanced.
