What to do now? 9 days left, GPrep: 750,730 PR: 730,750,780 MGmat:690

Hello,
Sorry for the long Post. I have been preparing for Gmat since last 3 months. I have done MGMAT guides , Og11,13,16 and 18 and some OG 18 verbal and quant review(whatever different questions i could find). Many things off Gmat club and really helpful for those(bunuels questions,topic wise SC and CR).
My princeton review test scores are: 650,750,650,740,710,780,750 towards latest ( I know the grading for these are flawed )
New Gmat prep online: 750,730
Old Gmat prep soft : 710
MGMAT free test: 640, 690(retake)

All this sums up to Quant above above 48 except MGMAT(45) and verbal 38 to 43.
I cant figure out any strong or weak areas per say because the results are varying so much. Sometimes i do all the SC correct and fail in CR or may do CR with 90 to 95% accuracy and flunk in RC. I feel its all coming down to luck. Can anyone please suggest me the best way to go now in these last days to get maybe a 10 or 20 point improvement and what material to follow for that. Thanks.
