Need suggestions for the third attempt.

I have the in center exam planned on 15th of September, and this will be my 3rd attempt. After getting 590 with Q47 V25 on last attempt, I am still on the journey to achieve the 700 mark. I went through the official guide once again, studied Manhattan guides for CR and SC, and attended several webinars hosted by Gmatclub. The most recent scores I have received in mocks are: On Gmat prep1 the score was 710 Q50 V35 (although it was a retake, I didn't remember the answers to questions.), On LBS Economist mock the score estimate was 710-750 with V39 and Q 50. The other mocks I took were from The Princeton Review, took total of three tests and the scores are: On 1st test V 34, on second V35 and on third V37. I also took one free mock from 800 score, and I got an unexpected V 43 ( I think the questions were rather easy, and the score is inflated for sure).
After analyzing the mocks, the concerning section is RC in which out of total of 13 questions I get 5-6 questions wrong and I think this is what holding my score back.
I have checked the accuracy of the questions from official guides.
On easy questions: 80-90% accuracy.
On medium level questions: 70-75% accuracy.
On hard level: 45-55% accuracy.
I am looking for suggestions from the experts on what strategy to follow in these last 20 days.

Your suggestions are highly appreciated.
Thank you in advance.
