Best Book for Practice Tests?

<p>I already have the Real ACT book (the red one), but which one of these are closest in accuracy to the real test?</p>

<p>Kaplan
PR
Barron's
McGraw-Hill</p>

<p>Thanks.</p>

<p>McGraw-Hill is too easy and PR, Barrons are usually considered to be too hard. Idk about Kaplan.</p>
