What ONE thing would you do to prepare for ACT?

<p>If you were only going to do a limited amount of preparation for the ACT what would it be? For SAT's my son did a few practice tests in 10 Real SAT's, studied vocabulary and read "Up your score". I don't think he is going to do even that much for ACT particulary because he is planning on going standby for the ACT. He was weakest in math on the SAT. So what have people found to be the most beneficial study tool for the ACT? Thanks.</p>

<p>Take a practice test.Then another one.</p>
