Ok, I have been posting a lot recently. I hope my GMAT practise scores would be directly proportional to the number of posts(just kidding,bad joke

)
So, I took my third
MGMAT CAT today and scored a 590. I'm not happy but I'm relieved that there is some progress.Unfortunately, my individual section scores are not really steady. I need your suggestions/opinions on this.
The schools that I am targetting need a 620-650, apparently the mid-80% range has in increased to 640 from the earlier 600. I need to make sure that my scores stabilize to 650.
Here is the break down:
MGMAT CAT 1 520 Q40,V21 --- got almost all RC wrong ----------22 jan
MGMAT CAT 2 530 Q33,V31 ---I feel the Verbal score may be fluke,got many CR right ---29 Jan
MGMAT CAT 3 590 Q44,V27 ---I guessed on 2 quant quest, RC accuracy is up, CR and SC are down--------8 feb
