I took the gmat almost a month ago a scored a brutal 580 without much studying. I've been working on my Quant skills for the 30 days since that exam, and have done 12 of the GMAT Club Quant exams. Is it normal that I am absolutely getting killed by these exams? I'm scoring approx 12-20/37. Doesn't seem like I'm improving either
Just how difficult are they comparatively?
