Hi gmat_winter,
It sounds like you've defined your goal score (710+), but I'd like to know a bit more about your overall timeline so that I can help you put together a plan to get to that score.
1) When are you planning to take the GMAT?
2) When are you planning to apply to Business School?
Most Test Takers need 3 months (or more) of consistent study time to hit their goals; during that time, it's common to spend 10-15 hours per week studying. Overall, it's a big task that can be broken down into lots of little pieces.
As the other posts have mentioned, you're probably going to need more practice materials than the ones that you listed. Before we figure out which ones you'll need, we need to get a sense of your current abilities, strengths and weaknesses. As such, you should take a FULL-LENGTH practice CAT (you can download 2 for free from
www.mba.com) and report back with your scores. That data will be useful in helping you to put together a solid study plan.
If you have any specific questions, then feel free to contact me directly.
