Hi Zach,
To start, a 700 is an outstanding score (it's right around the 90th percentile overall), so you should plan to apply to any Business Schools that interest you. Unless you're planning to apply to a highly competitive Finance Program or other Specialty Program, the Q44 will probably not be an issue (remember that you need a strong OVERALL application, so your time might be better spent working on the other parts of your application). To that end, how do you KNOW what your target School is 'looking for?'
That all having been said, a Q44 means that you're likely really good at the straight-forward 'math' questions that you faced on the GMAT, but you missed out on lots of strategy-based points (especially in DS) and you likely made a couple of minor mistakes on 'gettable' PS questions. To raise your score to a Q49+, you'll likely need to focus more on your Quant tactics (and not your knowledge, nor simply mowing your way through lots of additional practice problems).
With an October 8th Test Date, you have about a month of study time, which could be enough to help you to hit your goals.
1) When are you planning to apply to Business School? (if it's for Round 1 this year, then what is the application deadline?)
GMAT assassins aren't born, they're made,
