My Strategy for a 700--any pointers?

Ok here is my GMAT situation, I feel like it is very different than most of the members of this forum. I am a native English speaker and have lived in the U.S. all my life. I am strong in my verbal abilities, but quant is the section that gives me the most trouble ( I got a 40 on my MGMAT CAT #1). I have never been very good at math, I struggled throughout high school and college, but managed to make it through calculus. I’d like to post my strategy for some comments and helpful tips oh how to crush the GMAT. I am shooting for a 680-700 with 3 - 4 months of study time, and I got a 610 of my MGMAT #1 (40q, 34v). My quant breakdown for MGMAT CAT #1 is as follows, PS 50% correct, DS 64% correct. My worst subject areas were Geometry (1 out of 3), Algebra (4 out of 9), Word Translations (5 out of 10). I believe I struggled in geometry because I could not recall alot of the formulas that were being tested. In the quant I moved at a good pace and did not leave any blank. My verbal breakdown is as follows, SC (80%), RC (50%), CR (43%). Completed all questions.


My Materials

-Kaplan Premier 2008
-All 8 MGMAT Guides (except CR)
-Powerscore CR
-OG12
-OG11
-OG Quant
-OG Verbal

My Strategy

Phase 1 (Strategy and Quant)
- Go over the Kaplan Premier strategies for quant.
- After Kaplan, begin studying quant concepts for MGMAT (Start with NP end with Geometry)
o Weekdays study 1.5 hours of MGMAT strategy book, do 20 questions from the OG (timed). Review results and explanations the next day. Keep an error log.
o Continue this process through all of the MGMAT Quant books.
- (I know this will take me longer than a month)
Phase 2 (Verbal)
- Go over the Kaplan Premier strategies for verbal
- Study the verbal concepts in the MGMAT books and Powerscore CR, begin with SC end with CR
- Also read The Economist daily to help with RC.
o Weekdays study 1.5 hours of MGMAT strategy book, do 20 questions from the OG (timed). Review results and explanations the next day. Keep an error log.
o Continue this process through all of the MGMAT Verbal books.

-Another Idea I had was to completely review one MGMAT quant book, then switch to a MGMAT verbal book, and continue this pattern until I am through with the whole set. With this strategy I would try to take a practice test every other week. Any thoughts on this strategy, or should I stick with the more conventional one?

Phase 3 (Practice)
-Take 2 practice tests per week with a thorough review of errors
-Finish OG and review the error log on the remaining days.
-Review some strategies for AWA.
-When the test nears I will take the GMATprep tests as many times as I can as suggested by many.

Do you think if I stick to this strategy I could achieve a 700????

Please comment on this strategy, I need some pointers.

Thank you!
