This is a very nice set of books with interesting mathematical problems at the high school level.
Working through these problems is a good preparation for more advanced problem compilation books.
These are some notes and solutions that I came up with as I worked the problems from each year.

Readers unfamiliar with these books can see what others have said from the following links

As always, I am interested in hearing about any errors that might exist in this material.
