Writing MC - strategy help?

<p>Hi. I was contemplating whether or not to study grammar rules from Wren and Martin for the MC sections? Or should I just stick to strategies in the prep books (kaplan, princeton, petersons) I have?</p>

<p>I'm aiming for an 800 in writing, thanks in advance for your insights :)</p>

<p>Wren and Martin can’t hurt. The best bet is still to simply read as much as possible. This will strengthen your grammar skills, and help improve your reading comp. Good luck!</p>
