<p>What is, in your opinion the best practice ACT book? Practice tests are a must.</p>
<p>I loved The Real ACT Prep Guide because it's by the people that make the test. Three practice tests included</p>
<p>May I asked if you think it imporved your score?</p>
<p>absolutely...going over how to look at certain problems (explains this well) and working the practice tests under timed conditions really helped me with my pacing come test day. I used it for about a month before the April test and my composite went up 4 points from my original score.</p>
<p>also, i really think that being relaxed and confident on test day (and you can be if you've prepared) plays a major role. I'm sure someone else would agree with me here.</p>
