GMAT club test review.

I have preparing for GMAT since 1.5 month. Being engineer I have no much issues with quant, however to ace GMAT quant one need to have lots of practice and quality questions.
I took some Quant test on GMAT CLUB free on special holiday and found very challenging and difficult. Someone who targeting Q47+ need to solve as many test as possible. In my very first four test I got average Q39 however after reviewing each and every questions I found the pattern of quant questions. I analyse every question and ln one month later got Q 47. I have plan to complete each and every test to get enough confidence and competence. Gmat club quant test comprises 50% questions of 700 level
I would suggest every test takers to try at least 2-3 GMAT club test and compare with other quant test.
