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

Hi there, thanks for asking! I finished up to chapter 4, and just started the chapter 5 evens. I'll probably finish 1 chapter per week on average. If you enter your email at the bottom of the page you'll be part of my newsletter I use for announcing chapter completion.
All the best,
Shaun
