Art of Problem Solving got back to me. They recommend the Intro to Algebra Book (it's Algebra I & II) or Introduction to Counting and Probability. The first because it lines of up with his Algebra II material. The Counting book because it's material he won't have seen before but should be ready to handle.

I decided to order both. I expect that my son will enjoy the Counting and Probability Book better. He's one of those kids who doesn't seem the purpose in 'relearning' something. But I suspect the Algebra book will be a better book to him study for his tests.

As I am looking at this as supplemental, and my husband & I should be capable of answering questions I wasn't planning on signing up for any classes.

I just noticed they have online computer programming classes? Does anyone have experience with their child taking their programming?
