<p>For the ACT,
McGraw Hill sucks. I did one book with 10 practice tests and ranged from scores of 34 to 36. On the real September ACT, I failed miserably. The book was WAY easier. </p>
<p>SO,
does anyone know which prep book is the best? I heard Princeton Review and Barron are pretty good, but what else?</p>
<p>The Real ACT Book (Red Book) is definitely the best overall indicator of scores on the ACT, assuming you are taking the tests under a time limit. Don’t forget the free-annual ACT test prep. guide from your local high schools:)</p>
<p>The prep guide, to me, is also WAY easier than the ACT.
Maybe the September ACT was just harder in general? I don’t know. I was like AHH when I got to the test.</p>
