Hi texag15,
Many Test Takers are unhappy with their initial practice scores, but you really shouldn't be. That 460 is just a measure of your skills right now - and you'll improve on that result over time as you learn more about the content, Tactics and little 'secrets' of the Exam. That having been said, raising a 460 to the point that you could consistently score 700+ will likely require at least 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.
Before I can offer you the specific advice that you’re looking for, it would help if you could provide a bit more information on your timeline and goals:
1) When are you planning to apply to Business School?
2) Going forward, how many hours do you think you can consistently study each week?
GMAT assassins aren't born, they're made,
