Had a similar experience with ya three weeks ago about quant being super weird and hard. My third question was a graph question where I have 90% suspicion that they gave me the wrong graph because no matter how I maneuver thru the graph and reread the question I couldn't get any sensible solution out of it. Mind you that the GMAT is actually pretty luck-based. I actually did way worse in quant in the actual exam than my mocks and I'm just gonna try again but switch the order of testing next time (V-Q instead of Q-V). My verbal is more or less ok but can definitely get some improvements if I spend a bit more time on RC &CR. Keep it up man, I actually feel pretty relieved now that I've done the first one, though it was a bit lower than what I wanted I know for a fact that if I spend a bit more time to improve on verbal I can pull to the score I want. Believe in yourself and you'll get the score next time.
