Hi Tom,
Using your recent CAT Score as a gauge, you could pick up all of the missing points that you're looking for in just the Quant section, so you could focus most of your time on Quant (while still doing some Verbal work). In addition, many Business Schools view an Applicant's Quant Scaled Score as an indicator of how that Applicant might handle the 'academic side' of the Program, so you'll benefit in multiple ways by raising your Quant. That having been said, your current Quant Scores show that you're pretty good at most of the 'math' questions that you face, but you're making some little mistakes and you're missing out on LOTS of 'strategy-based' points. However you choose to proceed, you would likely benefit a great deal by working with materials that focus on Quant Tactics and patterns.
Most GMAT Companies offer some type of free materials (practice problems, Trial Accounts, videos, etc.) that you can use to 'test out' a product before you buy it. We have a variety of those resources at our website (
www.empowergmat.com). I suggest that you take advantage of all of them then choose the one that best matches your personality, timeline and budget.
If you have any additional questions, then just let me know.
GMAT assassins aren't born, they're made,
