GMAT Club tests: A must for Q49 or above

I recently appeared for the GMAT and score 700 (Q49 and V37). Though i am from an engineering background, cracking gmat quant questions was not a cake walk for me. I started my quant preparation with OG . As my preparation progressed, i realized that OG will not help me reach 90%ile in quant. I was looking for the material that could prepare me for quant 700 level questions and then i came across GMAT club quant test. Though the level of the test is a touch higher than actual GMAT, it prepares you will for the exam.
With my experience with GMAT club, i strongly recommend anyone struggling with quant to target 700 level questions with GMAT club tests and explanations by Bunnel. This strategy has worked for me & hope that it will help others as well.
