Strategy for Final 3 Weeks

I'm at the three-week mark before D-Day. Does anyone have advice on whether I should focus more on the Quant section than the Verbal Section?

Below is a list of my practice GMAT scores, in order of oldest to most recent. All were taken under timed test conditions, and I did the AWA and IR section for each. My goal is a 700, but no tears will come with a 680.

• Veritas - 590 (Q35/V36) - Quant 36 percentile, Verbal 79 percentile
  Kaplan - 600 (can't find breakdown) - Quant 57 percentile, Verbal 74 percentile
  Princeton - 610 (Q40/V34) - can't find percentile breakdown
  MGMAT - 640 (Q39/V38) - Quant 46 percentile, Verbal 84 percentile

I know scoring higher in the verbal section affects your score more, but I feel like my quant section is really low. I was thinking of applying a 2:1 method to my studies. 2 days of quant for every day of verbal. Or would my time be better spent trying to get over the 90 percentile for verbal? I know my weak points in both sections, specifically SC in verbal. I still plan on taking more practice tests, including the GMAT official tests.

Any advice on where I should focus the bulk of my time or if I should just split it evenly, would be greatly appreciated!
