I took the gmat just today , the 13th and was shocked by a 540 despite I aimed at a minimum of 650 - 700 and studied for 3 months . Intending to retake after 4-6 weeks , I am in urgent need of your valued advice . What shall I do ? I have to mention that I identify and categorize 80-90% of the questions I see , and for most of them (saying 70-80 %) I can strategize the required approach.

Thanks
