I think the main difference between GMATPrep v/s
MGMAT on the verbal section is the kind of CR questions. A lot of those on
MGMAT are quite different than the real thing, where you end up getting stuck between two answer choices which seem equally good and the reasons for which are equally subtle. On the real thing, most CR questions are much more straight forward, so level of difficulty is lower. The SC bit is pretty much the same between the two. The RC, again quite similar, but on the
MGMAT there are certain question types which are quite common like "what is the tone of the passage", these are generally hard to answer and not that common on the real GMAT, atleast not on mine.
My recommendation to you would be :
(a) Practice quant : Not necessarily doing problem sets. If you are at q47/48, getting to 50/51 is just minimizing error rates. Give more CATs and try to spend more time per Q to increase your accuracy.
(b) Verbal : My weakness was SC ... and I found brosing through the SC forum here very useful, just doing a random set of questions. But this was after I was done with
OG and
Verbal OG both.
