Improve from 660 to 700+ in 2-3 weeks

I took my first official exam several days ago with not satisfactory score 660 (Q49, V32, IR6). My goal is 700+.
I had 7 minutes in the end of Quant section. I rushed to end Verbal part. I picked the answer for the last question, but not pushed Submit. But in ESR I can see that I finished 41 questions.
In the day of test I jittered very much, then I calmed down, but before Verbal I started again. I ate banana between section, but at home I never did it (never ate, but drink during sections).

I studied till April 2016 with Manhatten books, but without practice and not regularly. In April 2016 I started e-Gmat and practise tests. I studied for 4 months quite hard (as it possible with long hours).
But the last month or something like that I concentrated on Math part without repetition of Verbal part. I had not enought time to repeat anything before the test, I hardly ended theoretical part. I didn't have enought time to study IR part.

My scores on simulation tests:
Official GMAT pack 1 - 490 (V19, Q - don't remember) in 2014. My first attempt, I even couldn't translate all terms (geometry, for example). I am not native speaker.
Then I reinstalled program and did pack 1 again.
CAT 1 Manhattan GMAT - 590 (Q44, V29, IR 3.17) - april 2016. I finished all manhatten books, but have no practice.
CAT 2 Manh - 640 (Q42, V35, IR 3.94) - july 2016
Off GMAT pack 1 - 710 (Q49, V36, IR 5) - Aug 8 2016. My break before Verbal part was 3-4 minutes longer. First time I didn't rush to the end Verbal section, I had 2-3 minutes in the end. Quant I think too. I didn't remember questions from 2014, so it was new for me.
CAT 3 - 600 (Q39, V 34, IR 1.63) - Aug 20 2016. But in that day I had headache and was not really prepared for long test.
Off GMAT pack 2 - 650 (Q48, V32, IR5) - Aug 21 2016. IR part was the same as of pack 1. I had 9-10 minutes in the end in Quant section.
I took always the entire test with IR and AWA at home. My table at home looks like table in test center (not 100%, but feelings were more or less the same).
I took tests always in different time, but in the mornings. My real exam was at 12 pm.

My percentile for CR was 98th, I didn't expected, but was 50 for SC and 47 for RC (unexpected low). I think CR is a chance only. My first set of questions was right only in 50%, even for last it is 63%. But in the last section I guessed for last 3-4 due to shortage of time.
For Quant score for algebra and geometry was higher than for arithmetic.
I saw 2 or 3 questions on quant that I couldn't answer.
See my ESR in attachment.

Please, advise me on what part I could concentrate to improve my score in 2-3 weeks, I don't have time, because I want to jump in the second round in this year (class 2017). What will be more "profitable" - to try to improve quant to 50 or 51 or improve Verbal part?
