Reddit reviews Pre-calculus Demystified, Second Edition

Do you have a Kindle?(no experience with other e-readers so don't know if they're available on other formats.) If so, there's free textbooks (think they're called ck Pre-Algebra, Algebra I, Algebra II and that should get you ready for Trig and scratching the surface of Calculus) from Pre-Algebra up to Calculus. They're fairly decent, I used them to refresh my Algebra before I took an intermediate algebra course and I finished the course in 3 weeks (as in my instructor let me take the final 3 weeks into the course). I'm working on Trig and College Algebra now and I like Larson's textbooks for guiding me through and www.larsonprecalculus.com has short video lectures and worked out solutions to the odd numbered problems if you get stuck. They're too pricey for me to recommend unless you can pick one up for under $20 bucks though.

As supplemental materials I'd suggest Pre-Calculus Demystified and as always khanacademy.org for practice problems.
