Just came back from exam center. Got a score of 740 (97 percentile) 49 Q, 42 V.
I thank GMAT club team for incredible opportunities the website provides to meet some of the brightest people in the world. I am 100% sure, some of the guys (of course girls too

) here are very bright. I must say I met more no of bright people here than in my entire life, before joining club. It is with their help in terms of advice, and encouragement, and of course my own hard work and god's grace I could improve my score.
I thank Laxie, NCPrasad, Kripal, Swagatalakshmi, GMATT73, dwivedys, Kevincan, HongHu, Rahul (the guy who posted CR1000, RC1000, SC1000 in gmatclub) particularly.
You guys are awesome !!! You make this club a wonderful place
Coming to GMAT journey here are scores of my past attempts.
1st attempt (in 2001): 600
2nd attempt (in 2003): 670
3rd attempt (in 2007 march): 670
4th and final attempt (today

): 740
I have been around GMAT club for around 11 months. Joined with a score of 670, after 2nd attempt.
I shall try to be as objective as possible. Hope my experience will be useful to somebody.
The only difference between last time and this time is, my practice of the material in test mode. 1000 series posted by Rahul has been my bread and butter in terms of material for the last 4 months. I completed almost all of RC1000, 90% of SC1000, and 70% of CR1000. I used this 1000 material for creating tests. I took around 40 full length tests (including writing essays) in this manner. Manhattan SC book has been a useful guide too.
Practiced one test everyday for 4 days a week. I will explain why I had to take this extreme step. When I took GMAT for third time I noticed that I am almost getting tired in the middle of verbal. I could feel the fatigue that was creeping in. Mind went blank. Could n't think clearly and was forced to read the same information again and again. And due to that fatigue, under time pressure I was forced to choose an OK answer. Then I tried to address the problem during my preparation. I had marathon runner in my mind when I thought about this problem. What would a marathon runner do if he wants to increase his stamina to run more than 15 kilometers? Ideally he would practice the same distance everyday. Not 1 km one day and another 1 km another day and so forth. He will have to run entire distance as many days as possible to build stamina. I tried to replicate the same thing in my preparation. It was painful initially. You wound n't want to sit and take a test for 4 hours after working in office for 8 hours. It is tough. You feel like crying when your are trying to do that. But we have to have that stamina. I think that is worth the effort.
I guess that is what is expected of us as senior executives tomorrow. Ability to take mental strain for extended hours is essential.
GMAT club helped me in getting advice, and material. Here I could benchmark myself against the best. When I was reading some CR responses of NCprasad, I was just amazed at his clarity of thinking. He was the benchmark I had. He suggested that I go through LSAT CR to crack CR. I did so faithfully. Must have solved more than 600 LSAT CR problems. He suggested that I take verbal questions randomly like 1 SC, 1 CR, 2SC, 1CR and never more than 2 questions of the same type. I did as suggested. This condition is limited to SC and CR. Obviously, for RC we can't do that. LSAT RCs helped me a lot.
One solution I can suggest: To improve in any section one needs to practice as many tough questions as possible in that section.
One caution: GMATclub forums can definitely complement your preparation. But they can't replace your own preparation. In my opinion, forums are not meant for that.
If anybody has any question, please feel free to PM me. I would be glad to share my understanding.
Thank you.
