McGraw Hill tests?

<p>I've been taking the McGraw Hill tests in their "10 tests" book, and I was wondering if anyone had any reviews of the book. Overall, I think it's pretty accurate, but I have questions about the Reading and Science questions. I am a faster reader, but the passages seem a little shorter than the actual ACT, and the science tests in the book seem to me to fluctuate in difficulty (i've gotten 25-35's)... so... any opinions?</p>

<p>I think the curves are inaccurate (they're quite different from the ones in Real ACT, so I'm judging on that). Math seems to be easy, but I don't know for sure since I haven't taken the ACT for real yet....could just be me?</p>
