I personally think MGMAT PS questions are not really representative of the real GMAT, maybe they are just trying to make their material stand out, Also i disagree wth a lot of there CR questions in the CATS, slowly and slowly i am realizing that OG rules and every thing else just plain SUCKSSSSS...be it MGMAT...Kaplan
...Princeton...anything else. putting tough questions is no big deal but putting the questions representative of the real thing is the point where all of them totally fail, for quants nothing comes even close to GMAT Club challanges as far as practice is concerned.
Also, MGMAT quants solutions are pathetic, i can solve any question in a shorter way then they do.
adding to this :
Also, i feel that the level of toughness in Kaplan
tests is a lot more balanced as compared to MGMAT even though i scored 600 in kaplan
and 720 in my last MGMAT, so if you forget the screwed up kaplan
scoring algo but take there raw score and try to match it to the Gmat prep scoring, that could possible give you a very good idea.
I totally disagree with MGMAT scoring, i scored 49 in quants in my CAT yesterday with 13 questions wrong, now thats Bull..sh...its inflated for sure.
