decaying CR score

<p>I've been using the grammatix method for CR since this summer. 3 weeks ago I got my CR to -1 or -0 every time I took the 10RS (2nd edition). But yesterday, after not having done any CR questions for 3 weeks, I got a -7 in the 10 RS (4th ed). So my question is ***. Does this mean I have to practice with the grammatix method constantly? has anyone else experienced a similar situation?</p>

<p>Question...when I first got grammatix and read over the CR part, then did practice questions I got them all correct. Now that doesn't seem to be the case...what happened? How are you supposed to incorporate Grammatix, because right now I'm questioning my $50...and mike has yet to answer my questions/send me a hardcopy</p>

<p>grammatix for me, is just gimmick. for one thing, it doesn't really teach you anythign kaplan or PR doesn't already. and 2ndly, its methods alone will NOT get you 750+. Don't expect grammatix to be some kind of "miracle" prep where anyone who practices it gets 800</p>

<p>that's not the problem. the thing is I did 4 consecutive real SAT tests 3 weeks ago and my CR score was around 760-800 range; now I'm in the low 700, high 600 range.</p>
