So far did it the first time yesterday and got 530 (q36 v26). Missed a clock for several times and this resulted in random-clicking on 5-6 questions in the end (clarification - this is about math part!). Got the mood down as a result and while had plenty of time got the awful result of 26.
However, as Edison said, our greatest weakness lies in giving up and the most certain way to succeed is always to try just one more time. I will do again in October, considering to review completely strategy and barron&
mgmat books.
MGMAT btw a day before the exam was over 600 (don't remember how much) but the real questions were much harder.
Good luck to you buddies in this exercise.
