May 18th test. 11 more days. Need opinion on focus

[fangtray]

hello, i have my exam on may 18th. I imagine I will do 0 GMAT on the 17th, and perhaps very little if at all, on the 16th. which really leaves 9 more days of studying since I live in Guangzhou, China.

First Prac Exam from GMAC 700 (48 quant, 38 verbal)
Second Prac Exam from GMAC 710 (49 quant, 36 verbal)

Manhattan GMAT Prac Exam 690 (45 quant, 38 vebal)
Retake of Prac Exam from GMAC (taken yesterday) 730 (48 quant, 41 verbal) - probably inflated since I saw some of the same verbal questions, although, upon reviewing, i got them all wrong again. For quant, all 37 questions i have never seen before... perhaps this suggests something about GMAT PREP 2.0 from 1.0? So i feel my 48 quant is a somewhat accurate predicter.



My question: In my last 9 days of studying, should I take another practice exam? Or should I just focus on OG questions that i got wrong and my weaknesses. I purchased the extra 400 questions from GMAT PREP 2.0, so i have a lot more OG questions i can practice with.

I'm want at least 700, but would be extremely happy if i could get 750. From my practice exams, it seems as if i'm not even improving.
