To try to improve my quant score (39), I went out and bought a PR GMAT book for the quant section. Apparently, they recommend a focus on time in the beginning with up to 3 minutes per question with a very high accuracy goal, and then subsequently decreased time and lower accuracy goals in the later questions.
My Kaplan class
never really addressed this, and I have seen more posts that claim the GMAT is accurate even at the end of the test in adjusting your overall score, so this leads me to two questions.
1) Have you had success with the above mentioned PR strategy?
2) Does the GMAT tend to change your score less in the later portions of the test, do you think it can can accurately adjust even through the end?
