I took my GMAT yesterday (December 5, 2011) and got Q48 and V36. With the limited review time that I had, Im pretty happy with the score that I got.
So here's how I did it (In case someone out there has the same case of not having ample amount of time for review).
First, set your goals! Be positive but be realistic as well.
I think I'm pretty good at Math. So seeing the types of quant questions, I knew that with a little review, I'll be able to get a fairly good score at the quant section. Now the verbal part is a different story, I know that to get a decent high score in the verbal section, I need a lot of time. But with two weeks, what should I do? I decided to focus on my quant. Learn as much as I can for the quant section and then give less time on the verbal section. I did this because I knew I can drastically improve my quant score in a week or so but I'll be needing weekS (or months) for my verbal. So I only had almost 3 days to review for verbal.
The most useful material for me was
the Official Guide 12. I solved ALL their quant sample questions. ALL of them! With this, I learned the typical question patterns and how much I had to learn per topic. I tried searching for sample questions in forums but I noticed that most questions posted in forums are way too difficult or you'll probably encounter them if your score is higher than 750! Again, be realistic!!! Haha! I knew that before reaching those difficult questions, I had to master the fairly average ones first.
Also, I downloaded the gmat club flaschcard in my iphone. It was very useful. And then, I made my own cards. I had little paper pieces that I carry everywehere I go. Some of them have sample questions, formula or whatever. My cards were very useful for reviewing as I can review them anywhere.
For my AWA, the 800 AWA guide was very useful. I found a pdf copy somewhere in the forum.
Lastly, on the night before my exam, I read the Princeton Review Manual. A friend gave me a pdf copy. It was useful as it covers all the possible sections and gave me a brief review of what I've learned in the last two weeks.
So there, that's how I prepared for the exam. Im pretty confident that if given more time, I can do better. And if I had more time, I would have studied differently. But overall, im pretty happy with the outcome.
On the test day, I tried to stay calm. I used all the break times to relax and calm myself. I think it is very important to manage your time during the test. For difficult questions, I guessed and moved on with the hope that they are one of the sample questions that don't really count.
Thanks to the gmat club folks, this site had been very helpful.
