Nice Outline
This is billed as an AP outline, but it can be used for regular US as well. The challenge is how? Obviously it is a good starting point for review, especially for a midterm or final. Students could also use it to make detailed outlines as the year goes on. It is made by REA which, as far as I am concerned is the best AP US review guide out there.
