I took the GMAT and made Q31 and V32 and a score of 560, I want to move by score to 680, I am fairly ok with the concepts but I want harp more on strategy to tackle questions in 2 minutes and also get some exposure to tough quantitative question. I have the OG 11 and some of the manhattan series including the SC. What other materials will help to achieve my goal . Thank you
