The first thing that strikes me is the very large number of CAT tests you've taken, and the frequency with which you've taken them.
CAT exams are really good for (a) figuring out where you're scoring right now, (b) practicing stamina, and (c) analyzing your strengths and weaknesses. The actual act of just taking the exam is NOT so useful for improving. It's what you do with the test results / between tests that helps you to improve. Generally speaking, you don't want to take another test until you feel you have done significant work to improve the major deficiencies you uncovered after you took your last test.
If you've been focusing on taking lots of exams or doing lots of problem sets, then you aren't learning as much (or as efficiently) as you could be.
Your verbal was signficantly lower both times you did the AWA, so stamina is an issue for you. When you do take tests from now on, you must take them under full official conditions, INCLUDING the essays.
You can also practice stamina while studying. Schedule 2 hour practice sessions. Before you begin, plan out every single thing you'll do during the 2 hours. Halfway through, take an 8 minute break. Otherwise, work hard the entire time. Don't answer your phone. Ignore email. Don't even have anything to eat (except on the break). Push your brain to engage the entire time.
While studying, spend 1/4 of any given study period doing problems and 3/4 of the time reviewing and analyzing those problems. Most of your learning comes from your review and analysis, NOT from simply doing the problem in the first place.
You can use this article to help you learn how to review and analyze your work:
http://www.beatthegmat.com/a/2009/10/09 ... ce-problemIf you have not been reviewing problems in this way, then go back to problems that you've already done and start reviewing - all those OG and other books. You didn't extract what you could / should have if you weren't conducting an in-depth analysis of your work.
You're telling me accuracy for the three verbal areas, but accuracy in a non-adaptive setting and without time constraints is basically a meaningless statistic. Don't get so caught up in accuracy by itself. How is your timing? Are you able to work within the timing guidelines? What are your strengths and weaknsses when you do problems in an adaptive setting (so that you aren't getting a ton of too-easy problems)?
I will analyze my last 2 CATS and post it soon. Please let me know what do you think my problem areas are and how to improve my score to 720?
I can guess that you may not have been spending enough time on analysis previously, but I can't begin to answer that question with any detail until I see your test analysis. (Note: follow what the article says; don't post the data in the test reports. Do the analysis yourself and then let me know what you found out.)
