Self-Studying For AP Statistics

I may be studying for the AP Statistics exam junior or senior year, and I’d like some recommendations about what resources to use and how early to begin studying?

Best text: The Practice of Statistics
Best review books: Barron’s and 5 Steps to a 5
Useful Websites: http://stattrek.com
https://www.khanacademy.org/math/probability

Khan Academy isn’t AP per se, but the corresponding videos may help you if you’re having trouble grasping the concept from the book

Thanks, I appreciate the advice.

I am going to attempt to, but I don’t know if I’ll work up the nerve to take the test this May. I was planning on using an introductory course on MIT OpenCourseWare to learn the material and StatTreck to make sure I study the things needed for the AP test. Also taking an honors level class second semester.
