<p>The percentile shows how you fared compared to other candidates in the past 3 years on each section. I believe I got 9 wrong and omitted 3 for the verbal and still got a 93% - so clearly it’s not a percentage. Plus, the percentile curve for math is very skewed compared to the other two sections. That means if you get one wrong your percentile will drop considerably compared to Verbal and RC.</p>
