From what I've gathered, your quant score will be higher by a few points on the real GMAT vs. the
MGMAT. What I've noticed is that the really hard
MGMAT quant questions, are hard because they are long, not necessarily because they are technically difficult.
As you can see from my scores, the
MGMAT verbals are all over the place. I went from 99 percentile down to 75 percentile, even though my sentence correction skills have rapidly improved.
What I've noticed is that none of the practice tests really replicate the GMAT questions (at least from the 11th Ed. guide). I think the GMAT people take a lot of care to make the questions unambiguous. That way you spend less time trying to understand the questions. I think that has a real impact on the quality of the practice verbals questions (I've read a few explanations that left me scratching my head, while all the explanations for the real GMAT questions were quite straightforward).
