<p>I took the ACT in February and I got a 30, but I am retaking it in March due to state requirements. I used Princeton Review and the Official ACT book and this time around I have McGraw-Hill's 10 ACT Practice Tests. I was wondering if it's reliable? I looked through the English questions seemed off... maybe it's just me. But I was wondering if McGraw-Hill's is a reliable ACT prep book?</p>
<p>I wouldn't really say so. A lot of the English questions are ambiguous or downright wrong. You should be fine with the other books.</p>
<p>I actually think the McGraw hill practice book was pretty useful seeing as it was the first book of its kind that I bought.</p>
<p>Served me well enough for a decent first time score :D</p>
