Barnes & Noble has a plethera of pre-calculus prep books. Also, GRE Math is a good resource to have---it seems to be the consensus on SDN. For word problems, I utilized online lessons, and with Liponcott, Williams, and Wilkins text, and it helped a lot. For online lessons, I just typed words like "age and word problem", or "probabilty lecture notes" in the URL box and a number of links popped up. Also, Kaplan has a pretty thourough review, except in probability and statistics. All-in-all, though, Kaplan is the best bang for your buck. DO NOT GET BARRON'S---too many unaccounted errors in the ohter sections, that I would not trust it in math either. For example, I believe the equation it gives for variance, in math, is different than what's in other books. I believe Barrons says the denometer is "n", where I believe it should be "n-1"---just an example. Also, in the natural sciences section, the answer to one of Barron's questions is that catalysts alter the free energy---we ALL know that's wrong, but some may get fooled by Barron's wrong answer. Use Barron's for PAT and that's about it. Good luck!
