Hi 128,
Many Test Takers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so since you've been studying for just one week, so you shouldn't expect to have 'mastered' any part of this yet. 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 how you've been studying and your goals:
Studies:
1) What materials are you using?
2) Have you taken a practice CAT yet? How have you scored (including the Quant and Verbal Scaled Scores)?
Goals:
3) What is your goal score?
4) When are you planning to take the GMAT?
5) When are you planning to apply to Business School?
6) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
