GMAT Club Tests and Question Bank

I used the GMAT Club quizzes to improve my quant score and was very pleased with both the quality of the questions and the explanations of solutions. This aspect helped me tremendously in getting a better understanding of core concepts. I found them to be a little harder than the actual GMAT prep quant questions but it gave me extra confidence on my test day. Being able to focus on certain subjects or types of problems was also very useful during preparation. I did not use the verbal question bank as I found the gmat prep questions to be more representative of what I saw on the official test but the quant questions are outstanding.
