GMAT Strategy

Greetings,

Background: Non-native english speaker, spent about 5 years in the states, passed the CPA about a year ago, working in a big 4 accounting firm.

I took about 5-6 weeks off work to completely devote to GMAT. As such my plan is to go through 3 official guides (quant, verbal and full) and Princeton's "Cracking the GMAT".

I feel like in addition to doing the practice tests/questions/cracking_the_gmat I will need to dig in deeper into theory (especially in verbal). As such I am considering wether to study:

1) The 8 Manhattan guides
2) Kaplan Premier
3) Kaplan 800
4) The 3 Manhattan Verbal Guides
5) Any combination of the above

From my research it appears that Manhattan gives you stronger background in theory. However it might take me most of the time to go through all the manhattan books, wich will not leave me enough time to do all the practice questions/tests.

As such my question IS: is 5-6 weeks enough time to go through "Cracking the GMAT" and the Manhattan books + do all the questions from the official guides (all 3 of them)?

I took the Manhattan GMAT classes and thus went through all of the books. Found them very helpful as they address theory but also provide ample practice problems. On top of these practice problems, the MGMAT books list problem sets from the OG that pertain to the subject area in question. If you go through all of the MGMAT books for Quant or Verbal and complete all of the problem sets then you will actually be completing every single math or verbal question in the OG and Quant and Verbal Review texts. So by completing the MGMAT books it serves as a structured way to complete all the OG problems as well.

Disclosure: I'm friends with the CEO of MGMAT and he was able to hook me up with a great discount on my MGMAT course.
