Hi Dev,
With these recent practice CAT scores, and your overall score goal, high-level SCs are NOT what you should be focused on right now - there are far bigger areas that you need to work on to raise your scores. Given the Scaled Scores that you've listed, you will have to make some significant improvements to how you handle BOTH the Quant and Verbal sections - and that's going to take some time. You will likely need at least another 2 months of consistent, guided study to consistently score at the 710+ level, so you should consider pushing back your Test Date.
I have a few additional questions about how you took your CATs:
1) Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
2) Did you take them at home?
3) Did you take them at the same time of day as your Official GMAT?
4) Did you ever do ANYTHING during your CATs that you couldn't do on Test Day (pause the CAT, skip sections, take longer breaks, etc.)?
5) Did you ever take a CAT more than once? Had you seen any of the questions BEFORE?
GMAT assassins aren't born, they're made,
