I agree with cpepin. Very experienced test takers I know (Actuarial, medical school, etc.) all point to attempting it IN ORDER. Your mind will subconciously work on things you've glanced at and you'll come back at a question with a more experienced perspective.

My strategy: I make a good first pass, then I go directly for the "easier" ones I'm stuck on and knock those out of the way. Then the bulk of time remaining (say the hour you have left) to dawdle on the last 5 or so questions from 3 vignettes that are super tough.
