Hi NivenProfido,
To start, it's worth noting that to hit 470 on the GMAT, you do NOT need to correctly answer ANY questions that you think are too hard or too weird (so quickly 'dumping' those questions - so that you will have more time to spend on all of the other questions - would be a good idea). In addition, you are remarkably close to a 470+ right now, so you do NOT need to significantly improve in all areas to earn that Score.
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 your goals:
1) When you say that you "need" a 470, what does that mean exactly? Will that Score guarantee you entry into a particular Program (and if so, then how do you know that?)?
2) What application deadlines are you currently facing?
3) Have you actually scheduled your next attempt yet (for 10 days from now) or do you have the flexibility to schedule it for a bit later?
GMAT assassins aren't born, they're made,
