Why aren't all the problems on here?

You're probably asking about the even numbered problems? At the moment I'm covering all the odd numbered problems in order to cover chapters more quickly. After I'm done these (only 6 chapters to go) I'll return to the beginning of the textbook and cover the evens. It'll take a while though, and probably I'll complete sometime in the summer.

Best wishes,
Shaun
