Hi Mohit, that is quite a detailed experience you have posted. Clearly, time management was the issue here and as much as you could imagine, it can account for at least 25% of your overall score. You can be answering all questions from this forum right or from any paper test right but if you do not do it within the alloted time, you are into big trouble. While doing Kaplan, PR problems, I originally did not time myself and just tried to answer those questions with as much precision as I could without any consideration given to time. Wrong. Even when you do paper tests, remember to time yourself. Ideally, even when you do those individual bundles of verbal and math questions, make sure you time yourself.
As a rule of thumb, try to do SC under 1.5 min. and CR under 1.75 min. As for RC, spend about 2 min. reading the passage(approx 50-65 lines) thoroughly and about 1.25 min per question. If you are doing LSAT passages or CR, I would allow myself more time given the higher lever of difficulty of CR and also the longer RC passages. Given your actual verbal accuracy level, you should focus on RC. It is very boring but it is the only way to deal with your weakness. I at times studied for hours straight doing ONLY RC and doing about 5-10 back to back. You will see that after a few, your concentration level will go up and you will definitely improve your comprehension level. If you do not deal with your weakness, it will catch up with you during the exam time. For RC, read the "very very scared of RC" sticky in the "GMAT" forum. Eventually, you would like to bring your SC and CR accuracy level to 85%+ and RC to 75%+.
Although you should focus on verbal for the upcoming weeks, do not neglect math. Do not take math for granted; this could adversely affect your score. Join the math challenges as they are definitely good to keep your adrenaline up and your timing under check. Doing occasional math problems from this forum should keep those skills fresh.
Ultimately, in the week prior to the test, you should focus on CATs and participate less in the forum. You should limit yourself to 1 CAT per day otherwise you will just be drained. Also, spend about 50% of the time doing any test correcting it. So doing a 2h30 test, you should spend at least 1hr going over, not only your errors, but also the questions you got right. This will ensure that you learned the concepts rather than the answers themselves.
Good luck and let us hear about your success story.
