Very good. This helped me improve my performance in Quant.

This is my go-to GMAT prep materials in addition to the Official Guide. The variety of practice questions in GMAT Club Tests is hard to beat. I had to take the GMAT more than one time. I relied heavily on GMAT Club Tests for the later tests as I had exhausted several editions of Official Guide before taking my first GMAT test. I like both the Quant and the Verbal section of GMAT Club Tests, but the Quant section is my favorite among all the GMAT materials from all the other sources that I've tried. I found GMAT Club Tests to be very helpful and critical in my success in getting a higher GMAT score in my last attempt. Thanks a lot!
