Sorry for breaking it in to you - you have not really done anything yet to prepare for GMAT. So there is no reason to be disappointed. Based on your score and the amount of preparation you've put into it so far, you are probably a 700+ material. It took me over two months and many more actual hours of preparation to get 550
. But GMAT is structured and worded in such a way that you need to prepare for this exam specifically, not just try to wing it based on your general intelligence. So it's a no-brainer advice: just put in some preparation time. Especially if you feel like you did not have enough time, the best way to remedy that is to do as many test simulation as possible with emphasis on time management. I frankly think I am a 700 material too, if I had unlimited time on the test
. So just use many fine resources on this site to get some real preparation and CAT GMAT simulations. Best of luck to you on the next sitting.
