You could start with Wikibooks.  

http://en.wikibooks.org/wiki/

They are free, and you could start 3 seconds after reading this post.   They aren't complete, though, so you will still need to buy some books.   One place to find reviews when you are ready for college level courses is

http://apcentral.collegeboard.com

Click AP courses and exams (on the left), then teachers resources (on the right).  Click the course and material type "textbook" and it will give you  a list of AP textbooks, with a description and review for each.  You choose a few that could work, then google around to find a cheap copy.  Sorry, but I haven't found a good place for high-school-level textbook reviews.  

It would help to find someone with whom to discuss what you are learning .    I'll bet  a teacher or parent or guidance counselor could help you find someone to talk to.
