GMAT 480

I took GMAT class around 8 months ago, but due to busy schedule at work, I wasn't able to give time for gmat. 2 months earlier, I finally thought of giving GMAT a shot. I practiced Jamboree Practice tests (around 1000 questions on verbal and around 500 questions on Quant). My Quant section was very weak (I was an average student of Maths at school, but I wasn't that bad). I gave all the 6 practice test made available by GMATPrep, where my average score was around 550 only. When I appeared for the actual GMAT, I just got a score of 480 (Q32, V22). I was devastated by the score on my screen because I had at least expected a score above 500.


Now that I have thought and realized, I hadn't set my aim for getting a target GMAT score. I will of course appear for GMAT again, but I am not sure where should I start from again. During the past 2 months, I did work very hard and prepare for it by all means I could. Also, I am not an Indian who would get Q50 on their first attempt (Most Indians say they don't find Quant a problem). But here, my problem is both Quant and Verbal. Most of the people suggested me to go through the basics of Quant, and believe me I have gone through and know all the basics through (Jamboree, OG, Kaplan and Economist GMAT). The basics are done with, but cannot do well with the advanced .

Anyway, I am heading up for GMAT again and now my target score is 650 or more of course. Can anyone suggest me the materials I should follow or the area I should focus more or how do I do better on both the Quant and verbal sections? Help would be much appreciated. Thanks.
