WebWork:

I would like everyone to try the first assignment, which is called "Orientation"as soon as possible. These are some simple problems you should all be able to do, together with instructions on using the interface. I am not counting your score on this one, but I want to see that you've at least tried a selection of the problems.

I will put up a 'real' assignment in the next couple of days.
