Real ACT Prep Guide good enough?

<p>I'm taking the ACT on December 8th, and was wondering if you guys thought just buying the Real ACT Prep Guide was enough books? I've read that the book itself isn't good, but the practice tests are. Right now I have four practice tests, but supposedly the quality of advice in the book I bought isn't too great. Should I get Princeton Review or Barrons for strategy and/or subject review? I'm hoping to score over 26 on my first time.</p>

<p>Wasnt enough for me because I needed more practice questions.</p>
