Took the test today. Got 770. Other than OG and
MGMAT, I thank the GMATClub the most. As I have been working for the last 6 and half years and out of study for all this time, I had to revisit almost everything. GMATClub materials were of most help in this regard.
One thing I have to share. Don't know others feel the same or not: the real test is much different from any prep test. I took all the
MGMAT tests, all GMATPrep (Official one) tests, and free test of Veritas, Economist, and Kaplan. In the real test, Quant part was easier, but Verbal much more complex, especially SC. RC and CR were at par, though couple of CR got me confused.
My advice: prepare extensively, and take as many tests as you can.
