How to Interpret the Table

• Quantitative scaled scores are based on a 200-800 scale. (There's nothing magic about this number range; it's just GRE testing tradition.)
• Percentile ranking (0% to 99%) shows how you performed relative to all others taking the GRE over a recent multi-year period. A percentile ranking of 60, for example, indicates that you scored higher than 60% of all other test takers (and lower than 40% of all other test takers). NOTE: Percentile rankings are not reported to the graduate schools.
• One additional correct response makes the biggest percentile difference near the middle of the performance "curve" (because it's a typical bell curve).
• If you missed 5 or fewer questions out of 34, expect to rank in the top decile (10%) in GRE Quantitative Ability.
• If you responded correctly to 21 questions out of 34 questions, expect to rank near the 50th percentile in GRE Quantitative Ability.
