Hi Ataman,
Many GMATers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so if you are early-on in your studies, then you should not expect to have mastered any aspects of the GMAT just yet.
From your message, it is not clear how long you have been studying, but have you taken any practice CATs/mocks yet? If you have not, then it would be a good idea to take a FULL-LENGTH practice CAT Test; you can access 2 for free from
www.mba.com (and they come with some additional practice materials). That score will give us a good sense of your current skills, strengths and weaknesses and will help provide a basis for comparison as you continue to study. A FULL CAT takes about 3.5 hours to complete, so make sure that you've set aside enough time to take it in one sitting. Once you have those scores, you should report back here and we can come up with a study plan.
I'd like to know a bit more about your timeline and goals:
1) What is your overall Goal Score?
2) When are you planning to take the GMAT?
3) 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,
