Hi AnabelaCruz,
To start, you should STOP taking practice Exams. You've essentially taken a practice test of some sort each day for the last 11 days and that is far too many tests for such a short period of time. With that type of volume, you run the risk of 'burn out' before Test Day - and that is something that you want to avoid. This is all meant to say that you should stick to some light review for the next few days and try to get some extra rest (so that you can go into Test Day clear-headed and ready to work). All things being equal, you certainly appear to have the necessary knowledge to score 650+, so it's really just a matter of whether you're prepared to tackle the FULL GMAT under test-like conditions or not.
GMAT assassins aren't born, they're made,
