Plan - 1. Go through the OG11 for every part to get a general idea about everything in GMAT; 2. Focus on SC/CR/RC one by one; 3. Math is not difficult, but needs some time for the possibility part; 4. IR needs some time to get familiar with; 5. Writing is not a big deal. Format needs to be established, then requires some practice to utilize and repeat the format for different themes.
Parts 3-5 will be in comparatively lower priorities. But those will still be time-consuming. When possible, I should start preparing them asap. Parts 1-2 are the keys to obtain a high score.
Schedule - By Dec.'s end, I should complete SC part's detailed study. By Jan.'s end, I should complete RC/CR parts' detailed study. By Feb.'s end, I should complete IR/Math/Writing's detailed study. By Mar.'s end, I should have practiced for pacing using mock testing questions. Mar. 30th, 2013 is the day.
In Apr. 2013, with a high score, I will go back to visit family. In May. 2013, prepare for IELTS/TOEFL, most probably IELTS. In Jun. 2013, start preparation for application...Recommending Letter/Resume/Essays, etc. Fingers crossed for myself!
