Inconsistent scores in Mock Tests - GMAT on October 11

Dear All,

I have GMAT test on October 11, so only 12 days left from today. My mock test results have been inconsistent as below:

Veritas Test 1 - 650 (Q-47, V-33) // August 26
GMAT Prep Test 2 - 720 (Q-50, V-38) // September 17
Veritas Test 2 - 660 (Q-50, V 31) //September 22
GMAT Prep Test 3 ( EP 1) - 660 (Q-48, V-34) //September 24

I am making some silly mistakes in Quant section and missing out from Scoring 50 in some tests, and hence the overall test score is going down. Also in verbal, I am unable to cross 35 except in GMAT Prep2. In verbal, I am getting around 11 questions wrong on an average ( sometimes I screw up SC with 5-6 wrong in 17 or sometimes CR with 5 wrong in 11, but RC is ok, 2 wrong in 13-14).

Any advise what to focus on in these last 12 days, so that I can reach 700? I have followed MGMAT guides and OG and Verbal books. My plan is to go back to my error logs and Mock tests and see what mistakes I am doing frequently and work on them. Also plan to go through hard SC questions and revision of CR from OG and Verbal.

I want to apply for colleges in November ( Round 2 ending for almost all one year MBA courses)

Thanks & Regards,
Gannuswami
