hi, SimaQ,
your real potential is definitely higher than what the score of 590 reflects. So, I believe if you re-take it again, you are going to improve on it.
I guess my feeling during the verbal is the same as yours in the quant section.
In the verbal, i agree with you that the CR questions are more confusing than those that I've done, and the vocabulary used in the CRs is more technical. That got me definitely.
SC is GMAT-like, but I was bombarded by those long underlined questions, so i was not very confident about them especially under the tight time i have. RC is very conventional.
But overall in verbal, i am also not sure where I did wrong to get 34, as towards to the test i was scoring over 40 in the past 2 weeks. Or probably overall I didn't do well at all and got wrong questions here and there. So i felt i was meeting those tough questions, but no increase in its adaptive score.
Cheer up, no matter what your next step is, re-take or start applying. and let us know. Gmat score is not very important if you have a very strong working experience.
