Prep strategy for someone at mid-700s

Hi, I've taken 3 practice tests so far:

Veritas Prep Test #1 (February 8th):
710, Q46 V42

Veritas Prep Test #2 (February 21st):
740, Q49 V43

GMATPrep Test #1 (April 25th):
760, Q49 V44

Between the first test and the second test I just went over what what I did wrong on the first test.
Between the second test and the third test I went through Chapters 1-5 of MGMAT SC book (because I was weakest on SC) and looked at what I did wrong on the second test.

Now that I've taken enough tests to convince myself that none of the scores were flukes, what would be a good strategy going forward?
I've registered to take the actual GMAT on Saturday, June 13th, so I have about 6 weeks.

My original prep schedule was to go through the books I purchased, MGMAT SC and Kaplan GMAT 800, in the next 6 weeks, as well as take 3 more Veritas Prep tests and another GMATPrep test. However, given my unexpectedly high performance, would there be a better way to use my time? Is there a good way to focus on just the toughest problems?

Thanks,
