best act test prep book?

<p>Hey I'm studying for the MTS act test in Feburary.
What test prep book is closest to the real ACTs</p>

<p>A lot of the ACT prep books seem to vary in difficulty and content.
One example:
Princeton Review: Extremely easy. around 34 on practice test
Barrons: Hard. around 28</p>

<p>I hope the Princeton Review one is closest to the ACTs :).</p>

<p>Getting into the ACT has real ACT tests, but its tips are pretty basic.</p>
