I gave two tests of MGMAT and scored 660 and 680 respectively. I didn't really read too much into the one I got 660 because I wasn't really focussed while giving the exam. But, what bothered me was the difficulty level of questions on MGMAT. I found them tougher than OG. I practice around 50 questions in Quant on OG and mostly score more than 95%. But, when I started taking tests on MGMAT, I found Quant's difficult level to be higher. That made me question the validity of the difficulty level of the tests. What are your experiences regarding this?Kaplan
GMATPrep: Before any preparation 650.
On a side note, will retaking the first GMATPrep test result in duplicate questions? (I don't want to expire both the tests)
