So I took my first GMATPrep around a year ago just to see where I stood after breezing through the Princeton Review
"Cracking the GMAT
" book and scored a 640 (Q46, V31?). I took one again recently, like a month ago, after doing half the OG and scored a 650(Q43, V36). I recently enrolled in the Manhattan GMAT
Guided Self-Study Plus and took my first MGMAT CAT today and scored an 570(Q37, V31)!!
I felt that the MGMAT CAT was much harder than the GMATPrep CAT. Should I be worried or is the MGMAT CAT supposed to be, on average, much lower than the GMATPrep score?
