Good question - albeit a tough one to answer because it's just so broad to have "one" strategy that works for analyzing results. It's a little like being asked for the secret to success...there are many contributing factors and trying to list just one is always going to leave it woefully short.
The key to analyzing your results is to try to determine what you did wrong, and to pay attention to recurring mistakes. Some common themes include:
-Falling for "misdirection" in Sentence Correction (eliminating an unfamiliar-but-not-wrong idiom, for example)
-Missing the specific scope of a conclusion in Critical Reasoning
-Answering the wrong question (for example, picking a "true" answer but one that doesn't weaken the conclusion, if that's what you're being asked to do)
-Picking the effect in an RC question that asks you to provide the cause
I'd try to analyze your errors (or any questions on which you narrowed down to two and simply guessed right...you can't count on that kind of luck on test day!) with two themes in mind:
1) Why was the wrong answer wrong?
2) Why was it tempting?
You should notice that quite a few of your mistakes have a similar theme to them, and the following articles should alert you to some of the major themes:http://www.veritasprep.com/blog/2011/09/gmat-tip-of-the-week-planning-your-study-schedule/http://www.veritasprep.com/blog/2011/08/gmat-tip-of-the-week-three-essential-reading-comprehension-strategies/http://www.veritasprep.com/blog/2011/07/gmat-tip-of-the-week-three-essential-critical-reasoning-strategies/http://www.veritasprep.com/blog/2011/06/gmat-tip-of-the-week-three-essential-sentence-correction-strategies/http://www.veritasprep.com/blog/2011/05/gmat-tip-of-the-week-why-michael-bolton-would-fail-the-gmat/
