Hi Phhaes,
Many GMATers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so depending on the amount of study time that you have put in so far, you might simply need more repetitions in some of these areas to build up the 'familiarity' that you are looking for. You might also find it helpful to work through some of those questions types using the prompts in the GMATClub forums (and read through some of the approaches/explanations for guidance.
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied? How many hours do you typically study each week?
2) Have you used any other study materials besides the books that you listed? What “brands” of CATs/mocks have you used?
3) On what dates (or approximate dates) did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your overall goal score?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
