Hi luigi.roza,
These recent CAT scores are remarkably similar to the ones that described over 3 months ago in this post:
stuck-in-560-i-need-226534.html#p1742631This is meant to say that you're performing at the same general level as you were before - so another week of studying in this same way will likely lead to the same general result. GMAC has publicly stated that the Official Score that you earn on Test Day is within +/- 30 points of actual ability. Assuming a similar 'swing' in how your CATs function, your various CAT score results show that you essentially performed the same each time (+/- a few points). If what you described back in October is still the case now, then you're 'losing' too many points due to little mistakes, so THAT is what you have to work on. Given your score goal, you don't need to take any more CATs and you don't need to study anything new. Your big 'need' is precision. When you review questions that you've gotten wrong, do you ever re-attempt them (step-by-step) so that you can eliminate the original mistake that cost you the question in the first place?
GMAT assassins aren't born, they're made,
