Hi All,
I am writing this post in order to seek some guidance and help. My official GMAT is scheduled on Oct 24, 2018(I deferred my exam from Oct 9 though). I tried second GMAT exam today from mba.com/exam-prep and ended up with score 500.

I've been struggling with my scores from the very beginning and this is far the worst score I've gotten. I was in good condition though.I've been committed my time into this GMAT prep for last few months sacrifying my family. I feel even guilty now and really angry at myself. My verbal dropped from 30 to 21.
I would like to ask you all what are the chances that I will get score higher than 550 on my exam day. My target is not even high- just anything over 550.
I did several tests from Manhatten prep and scores were
510-530-540-550-550.
Also I did problem set in mba site and I got almost everything above average. Do I need to...give up now?
I have previous experience with CPA, FRM and CFA exams and had great success. I am so stressed. Any encouraing words or guidance would be highly appreciated.
