<p>I'm going into my senior year. I'm taking the ACT for the first time in September, then again in October. I'm thinking about buying The Real ACT Prep book (red book) and the Princeton Review book.</p>
<p>Let me know what you think, tell me what your experiences are with these books. Thanks.</p>
<p>The Red Book is the closest thing you will get to actualy ACT’s. IMO, its helped a lot. Are you looking for just the practice tests or also the review material?</p>
<p>Yes, the Princeton review and the red book would help you out the most. If you score 30 or above on the September ACT, also read Barrons 36 (it can be done in a weekend) and your score should then become higher to ~33-36. Good luck!</p>
