Hi BonesMBA,
First off, a 700/Q42 is an outstanding overall Score, so it could be enough to get you into your first-choice School. That having been said, 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 - and a Q42 won't impress anyone. That score implies that you did fairly well on most of the "math" questions that you saw on Test Day, but you made a number of little mistakes throughout the section and you missed out on LOTS of 'strategy-based' points. The Quant section of the GMAT is NOT a 'math test' - it's a 'critical thinking test' that requires lots of little calculations as you work through it. To score at a much higher level in this section, you need to become more of a 'strategist' and less of a 'mathematician.' This is meant to say that by focusing on Quant Tactics, you'll be better able to increase your GMAT Score AND better impress how Business School Admissions Officers will view your potential to handle their respective Programs.
Since you've named some highly-competitive Schools, you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement.
There's a Forum full of those Experts here:

1) How long have you studied in total? How many hours did you typically study each week?
2) What study materials have you used so far?
3) On what dates did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
