For the teaching-free week, the following are available on the web site:

* You should now also be able to complete the entire autumn 2005 set. Try it, and see how long time you need.

* Furthermore:
- Spring 2004 problems 1, 2 and 3
- Spring 2005 problems 1, 2 and 3
- Autumn 2006 problems 1 and 3


(You should also be able to complete the autumn 2004 set, as the Lagrange problem should be solvable using knowledge from 2200 
-- but even without this one, I have already assigned a total of three complete sets.)
