<p>I usually get around -5 MC, is reading more prep going to help me? I've read through Barron's 2400 grammar guide once. Should I read through Silverturtle's grammar guide as well? Or should I just keep practicing & reviewing answers? I really want to secure the 800 on this section, because I am confident in 770+M, but my CR is a little shaky (~700)</p>
<p>EDIT: I'm surprised that this is around a 680-700 score; just 5 wrong?! Even a 12 essay takes that up to only 730. I'm amazed.</p>
