Hi,
As the subject line suggests I got a 700 (M49 V36) on my recent GMAT exam. My previous score was 540. I studied for nearly 6-8 weeks (3 hours a day on weekdays and 6-7 hours a day on weekends). I also took good 15 days break from work prior to my GMAT.
My study strategy:
1) Went through all strategy guides of Manhattan G. Particularly, I must have gone through the sentence correction guide several times, I know a lot of the content by heart now :). ManG strategy guides lay a good foundation, especially for those who are working and have been out of touch with these concepts.
2) Skimmed through Kaplan GMAT Premier 2014 strategy sections. Did not find them so useful as my mind was attuned to ManG's strategy guide. Also, they are not as detailed as ManG strategy guide (in all fairness, can't expect one book to match up to 8 separate guides)
3) I am from India where we have a rigorous Math curriculum in schools. I used some of my school/college methods for certain topics (around 15% of topics).
4) Solved each and every problem of Kaplan 2014 Premier book (both math and verbal sections)
5) Solved ManG question banks along with examples and practice problems in each chapter in the strategy guides (more focus on Math)
6) Solved Math and Verbal Review (2nd editions) almost entirely. Solved half of OG 13th edition. Left out first few hundred sums. But I recommend that you solve each and every problem in all official guides for both sections.
7) Took 12 mock tests:
3 full length ManG tests
4 Kaplan tests
1 combination of Kaplan (Verbal) & ManG (Math)
4 GMAT prep tests (2 free + 2 paid)
My average and median scores were around 690. I wrote essay and solved the IR sections in each test, helped me build my stamina for the 4 hour grill. Final test day went smoothly, didn't struggle too much.
My scores in ManG tests were the worst. ManG math is really really tough. I ALWAYS struggled finishing the math section in time. I would have to blind guess on at least 7 questions (in some cases up to 12) in the math sections. All those who are taking ManG mock tests, be prepared for the grill. DON'T get disheartened if you struggle with your time. Make sure you revise and learn your from your mistakes. Make sure you solve each question you blind guessed on (after the test) and see the solution for all the questions you got wrong. Any number of tests you write will be useless if you don't spend time reviewing them. I used to take around 3-4 hours to review and solve and resolve wrong/flagged/guessed problems of the mock tests. It's okay to score low in ManG mocks, take it as learning experience, but make sure to LEARN from your mistakes.
ManG has a SUPERB review mechanism whereby you can use multiple slicers to practice your weak areas (by topic, by accuracy etc.). Use that tool to you best advantage.
Use a combination of Kaplan, ManG and GMAC materials to prep. These 3 are sufficient. Again, make sure you revise your mistakes - it's absolutely critical.
Lastly, PRACTICE PRACTICE PRACTICE! I practiced around 2000 problems (both math and verbal) (not counting the mock tests).
