Hi abudhabi1,
Many GMATers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so trying to compress a GMAT Study Plan into a much shorter period of time might actually work against your goals. In the broader sense, to answer your question, we need to define your timeframe and your overall Score Goal.
From your original post, it's not clear whether you are just beginning your studies or you have put in some significant study time already.
If you're just beginning, then it would be a good idea to take a FULL-LENGTH practice CAT Test so that we can assess your current skills, strengths and weaknesses; you can access 2 for free from
www.mba.com (and they come with some additional practice materials). If you want to do a bit of practice first, so that you can familiarize yourself with the general content and question types first, then that's fine - but you shouldn't wait too long to take that initial CAT. 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 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,
