We're using the term "easier" only because we're grading the passages on a curve. "Easy" is a loaded term. Therefore, its useful to think of think of the passages as those you'd do now, those you'd do later and those you'd never do.


POOD (Personal Order Of Difficulty) is an important test taking strategy. You look for what topics are easier and move on to harder topics.Even if the numbers are confusing the topic might be one that you know.


process of elimination to eliminate wrong answers that are clearly contradicted by what you're looking at.


  • All you need is reasoning skills.
  • Look for trends.
  • POOD and POE
