Hi bhdrb,
While answering most (if not all) of the earlier questions in each section is certainly beneficial to your score, you have to perform at a high level throughout each section to score at the highest levels overall. As such, you cannot afford to 'overcommit' to the first 10 questions in the Quant and Verbal sections. Since you're asking about this subject, I assume that you've put in some study time already. It would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied?
2) What materials have you used?
3) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores)?
Goals:
4) What is your goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
