GMAT Strategy

Friends,

I am looking for some concrete suggestions on improving my performance in RC. I have given 3 Kaplan CATS, 1 Veritas Prep and the 2 GmatPrep exams. My verbal scores are always below 35 and my accuracy in RC is hardly 40- 45%. I thought that if I improve in sentence correction and CR, I might do well in verbal section. However, this doesnt seem to be the case. My accuracy level is between 75 - 80% in both CR & SC. But because I am doing poor in RC, my scores are coming less.

So far I have scored the below:

Kaplan CAT 1 - 570
Kaplan Cat 2 - 640
Kaplan CAT 3 - 630
GmatPrep 1 - 670
GmatPrep 2 - 710
Veritas Prep - 680

I have done poor in all 3 Kaplan CAT verbal section with my highest score being 33.
My maths score in all exams has been in the range of 42 - 50. But verbal is causing a lot of problem.
I just have 1 more month left before I appear for the GMAT and RC is really making me nervous. I am not looking for a 700+ kind of score. Just a decent score between 620 - 670 is fine with me. But I think RC performance will hamper my goal.

I have already started solving the collection of RCs from GMAT, GRE and LSAT and I am taking notes. But I am not seeing drastic improvement in my test performance.
Can someone please help me with suggestions to improve RC? Your insights might really help me improve and achieve a good score.


Thanks & Regards
