Sorry guys... I took a vacation after the exam!! But I'm back to do my applications now!
The key for me was to time myself while studying... that was the main difference between my first and second time. I downloaded a desktop timer and timed myself every time I studied , no matter if it was a complete test or not. The week before the exam, I made a chart with the timing for the day of the exam by section ( e.g. you should spend 20 minutes in the first 10 questions of quantitative, 15 in the next 10, etc)
The second tip is simply using this amazing site!! I was very weak at verbal (since English is my second language) so I decided to focus on it for 2 straight weeks. I used the 1000 questions for each verbal section: CR, RC and SC, downloaded from here. After a week I realized how the answers for CR and RC appear or could be inferred from the text, you'll learn how to find the answers by doing a lot of exercises... after 500, they all start to look familiar and the answers are pretty obvious.
In terms of quantitative, I did the Kaplan course
but they didn't cover some exercises such as reminders, exponents and advanced geometry, so I used this site for that, and it was great!
That's all really, get a good night of sleep and contrary to what people say, I studied a little bit the day before, which gave me extra trust in myself.
Good luck to all!!
