I need help with applying Grammatix to the critical reading section!

<p>Hey Guys, </p>

<p>I am preparing for the Sat in October and I really need help in boasting my Sat Critical Reading Score. My score range for Critical reading is between 450-500. I started to use Grammatix because people keep on recommending it on CC. </p>

<p>The problem is I started to use it and I am having a very tough time in using it. I am still getting a lot of the passage based reading questions wrong using Grammatix's method.</p>

<p>Can someone please tell me how do I approach the Critical Reading Section Passage Based reading more efficiently by using Grammatix's method? </p>
