I take it two weeks from today so I feel you. I would say just drill the Official Guide from here on out. Make sure that you can do every problem in the guide. Also, make sure you can recognize what the problem is asking you to do. If you just make sure you answer all of the questions that you know how to do correctly, then you will get a good score. Just don't beat yourself on game day. Good luck.

1. Get the time management down first. You don't have much time to go through each session thoroughly.
2. Take practice tests - at least 3 before you take the final test.
3. Look for tips and strategies exclusively from different books. Our Turbocharge Your GMAT math and verbal books have chapters on tips exclusively. Kaplan is big on process of elimination. It can be helpful when you have very very limited prep time. You don't have enough time to work through all the fundamentals.
4. Focus on Sentence Correction on the verbal. For math, make sure you will use "12TEN" system to get your mind used to answering Data Sufficiency questions.
