grammatix or other prep books

<p>imm kinda confused .</p>

<p>i ordered grammatix ... and I have other SAT prep books at home ...should I even bother looking at those other prep books or should I just use grammatix w/ my blue book??</p>

<p>or should I do all those prep books then at the end use grammatix?</p>
