<p>i did the real act (which is the red book), kaplan, barron’s, and some online tests (and mcGraw-hill, but those were more for some fast practice).. the blue book for the SAT could work too.. yodadacoda is right - it’ll get your math mind around all the tricks of the SAT, and since there aren’t as many tricks on the ACT math, then you’ll be extra prepped</p>
