Math is clearly your strong point, so the trick there is to sustain your current level. In other words, the majority of your time and effort will need to be spent on verbal. For math, look into the GMATClub tests
and keep an error log
Verbal needs some work, so reread Manhattan SC and Manhattan CR
. Those topics - particularly SC - need to be read over and over again for the concepts to be fully absorbed. Also, see these links:critical-reasoning-question-directory-topic-and-difficulty-128861.htmlsentence-correction-question-directory-topic-and-difficulty-129750.html
Start with the 500-level questions and work your way up. Become an active member on the verbal forums. That means answering questions and fully explaining your answer.
For RC, I feel that the best approach is practice. And for tough RC passages, look into the LSAT.
I'm not sure how much time you have taken off from the GMAT since your first attempt, but try to take a break for two weeks or so. You studied for a long time and probably need a break.
How long did you study? - 2.5 months ( 45 days with focus and 30 days without too much focus)
You simply can't afford 30 days of inadequate preparation. Commitment is the most important part of your preparation. This is hard, I know. But if your goals are worth it, then you will find a way to do what it takes to reach those goals.
