GMAT Strategy

Hi team,

Here's a quick question - Should I stick to some specific material or Should I aim for as much questions and materials as possible ? By Specific material I mean, books which everyone refers- GMAT OG - latest edition and 10th edition, Manhattan: SC, CR and RC guides and GMAT Verbal Guide (latest edition).

Since, I have heaps of material for Verbal such as 1000 questions set each for RC, SC, and CR and books such as Kaplan 800, Kaplan Verbal Workbook and Princeton Crack the new GMAT, so should I target to solve as much material as possible or should I keep myself very specific regarding material for preparation. Which strategy will/can work better ?

For your better understanding, here's some more information,
* I can devote (or I am devoting) almost 4 hours in weekdays and 7-8 hours on weekends,
* I have been studying for last 1-1.5 months,
* Books I have completed - Princeton Crack the new GMAT, Kaplan Verbal Workbook (almost), and Read
Manhattan- SC, CR, RC guides
* Almost 40 days are left in my GMAT test,
* I haven't started practicing AWA and IR sections,
* I haven't started attempting OG questions,
* I haven't started giving Full Length GMAT mock test, and
* I believe that I am good at Maths - Referring score in Quantitative section

Please reply soon,
