preparation help

Hello everyone,

I have scheduled my test for 9th Sept and I was wondering whether anyone can provide some specific pointers on my preparation.

Here are my scores so far. I did not take a single test with AWA.

CAT name Q V Total
GMAT PREP 1 48 30 640
MGMAT 1 44 36 640
MGMAT 2 40 33 600 (after a lonnnnng vacation and 0 studying)
MGMAT 3 47 38 700
GMAT PREP 2 44 38 650
GMAT PREP 1 (R) 48 36 690
MGMAT 4 42 41 690
MGMAT 5 44 38 680

I have done few GMAT Club tests, and continue planning on completing them. My accuracies are not very high (60-75%). I have completed all MGMAT study guides. All OG questions from OG 11, Quant review, and Verbal review, except for the RC questions, as I am comfortable with them. I have repeated OG SC at least 3 times.
Using MGMAT CAT's, I found that I am having trouble with word translation, geometry, and 700-800 level questions; and I am also having problems with some tough SCs. I used to spend lot of time on certain questions, reducing available time for later questions, but I have learned how to give-up on some questions and move on.

Stuff I am planning on doing:
1- complete Jeff Sackmann's word problems challenge
2- complete Jeff Sackmann's extreme challenge
3- do some more GC tests
4- go over MGMAT word translation, geometry, and SC guide
5- complete GMAT Prep SC questions
6- give MGMAT 6, GMAT prep, and Knewton with AWA

I hope I have sufficient time to finish these tasks. If not, I will cut down on something.

All suggestions are welcome.
