Will grammatix help?

Test Preparation
1

<p>I'm looking to improve my scores by at least 100 points this summer and I've read that grammatix is great for CR. If I'm at a 690 right now for CR, will grammatix help me or will it only help me raise my score by a few points?</p>

2

<p>From what I know, it seems like it should.</p>

3

<p>Will it help bring up my 770 CR (kinda lucky score)?</p>

4

<p>what is Grammertix and where do you get it?</p>

<p>They say Grammatix is the best thing out there (besides good old practice) for CR.</p>
