Kornphan,
Practice. Practice. Practice. I took tons of practice verbal sections to hone reading skills. Also, I got up early before every sample test (I took Kaplan) and took a single verbal passage. It helped me to get my brain de-frosted and more focused for the exam. My verbal score went up 1-3 points on test day just because I was completely focused and used all of the nervous energy to rip through the reading more quickly. My best advice would be to have confidence in yourself and under no circumstances allow yourself to become flustered or intimidated by the test. Also, if you are really having a problem with the verbal sections, consider using Kaplan's strategy. I am teaching verbal for Kaplan now and believe me, their stuff works. Hope that helps. Good luck.
