GMAT Strategy

Hi All,

My GMAT is scheduled on May 11th.Till now I've completed the Maths basics,have done MGMAT maths sets once.I'm revising again those books and have done most of the practice sets from OG 13.
As far as verbal is concerned I've completed the Powerscore Bible once for CR and have practiced few questions from OG 13. For RC i've also practiced few passages from OG13 but I've not prepared SC at all till now. I've not taken any prep tests till now. AWA and IR are also left untouched.

I would like to complete OG 13,OG 11, OG quantitative and verbal and would also like to take the MGMAT tests and GMAT PREP tests.
My target score is 760.
I'm willing to study 6-8 hours in a day and I'm planning to get done with the basics by the end of March.I would like to devote the rest of the time taking tests and preparing simultaneously.

Please can anybody suggest a strategy of how to get completed with the basics and then take tests. When should I start taking tests . Should I study each of the 4 sections - Maths,RC,SC,CR everyday or should I assign few hours for each of these sections every week.

Please help me to develop a strategy...

Thanks in advance for your help.
