I took GMAT after 4 months of rigorous study: 640 (Q47, V31).
I have started preparing in March 2012 and started with a GMATPrep1 score of 540.
This score is nowhere near my target colleges average or median and very low for my profile. (Indian Software Engg./Male)
I will have around 20 free days off from my work in Dec around Christmas so i am planning to give GMAT a second try with a target to move to Q49/50 and V40+.
Study Material Used:
Quant:
MGMAT Quant Books
MGMAT Advance Quant Strategy Guide
GMATClub Tests (Now i know that these tests are closet to the real Quant)
MGMAT Tests
Need your valuable suggestions to help me with my Quant strategy:
1. The very first Quant Q looked easy but somehow (I was just staring at it

) i was not able to find the correct answer and took a educated guess. But after that i took a deep breath and pick up the pace. I was confident in answering most of the Quant Q's but guessed 2-3 Q in total to maintain pace (1 at each mile stone for my timing strategy). Also i struggled to answer few last Q's due to anxiety or nervousness even though i had enough time to solve them.
2. There are few areas which i am weak at e.g. Polygon/Stats/P & C/ Probability and decided to work on them. Any suggestion for study material and hard (Advance level) practice Q's for the same. I found that
MGMAT Quant theory is good for basic Q's and their Q bank is too tough for GMAT

Also it is not the right representation of GMAT Quant Q's.
3. I am still falling for 'C' trap and most probably did fall for C trap in few Q's for sure. Any practice material suggestions to master the subtle tricks and traps. I know the theory part of traps but find the application of that theory difficult to implement.
4. Overall how should i go about it? Considering my Verbal percentile i want to spend more time there but certainly i can not be satisfied with anything less than 90% in Quant.
