I got 3/8, 1 verbal 2 quant on the mba wedsite mini gmat. The raw score to percentile chart i found on gmatclub said that should put me in the 20th percentile which is about a 450. Why did i get a 370-390? Were the questions i got right easier? I need a 450 for suny new paltz. I read half of Princeton prep about a year ago and it did not help at all. I had taken a diagnostic and i believe it was a 380, but i am not 100% sure. Should i take another test as a diagnostic or just begin my prep? Would you recommend GMAT Premier 2017?
