Holes in the basics holding me back

<p>Unfortunately, when taking the SAT, I realize how my middle school and high school teachers left holes in basic things here and there–all depending on which teacher, particularly. Anyone know a really great and fast way to fill myself in on random essentials in arithmetic, Algebra, and just about any other math subject? Thanks.</p>

<p>How fast? Would a prep book be fast? lol. If yes, then try Barron’s because it supposedly “overprepares” you so you’ll get a good score if you look at all or most of the math sections. Basically, I used Barron’s, and the first time I took the SAT’s, I got an 800 on the math section. (Let’s not talk about critical reading though.)</p>
