Hi MarketerReese,
Many Test Takers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so after just 6 weeks of study, you should not expect to have 'mastered' any of the concepts just yet. That having been said, a 430 and 480 are fairly similar results (and the difference in those Scores might have been due to some lucky/unlucky guesses and/or silly mistakes that you either made or did not make). This is meant to say that you might be 'responding' to the GMAT in the same general ways - and "your way" might be keeping you from scoring higher. Statistically-speaking raising a 480 to the point that you can consistently score 700+ will likely require at least another 3 months of consistent, guided study - and you'll have to make significant improvements to how you handle BOTH the Quant and Verbal sections. Thankfully, the GMAT is a consistent, predictable Exam, so you CAN train to score at a higher level. With just 6 weeks of additional study though, there will likely be a limit to how much you might improve.
Since you're interested in 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 many hours do you typically study each week?
2) 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)?
3) When are you planning to apply to Business School?
