<p>Is the percentage purely determined by the total score? or by the combination of the percentages of three subjects? </p>
<p>In other words, is it possible that an identical total score (taken on the same day) by different individuals with different subject scores, gives different overall percentages?</p>
<p>Thanks.</p>
<p>It is interesting, I can’t edit my own post.</p>
<p>Anyway, just realized that I forgot a couple of important factors causing same score different percentage, grade and gender.</p>
<p>Subject scores are determined by scores within grade and sex. A male 8th grader with the same score as a female 8th grader may not have the same subject percentile, and a male 8th grader with the same score as a male 9th grader will not have the same percentile.</p>
<p>Not sure how they combine the 3 subject scores to arrive at the overall percentile.</p>
<p>I think they take the total score and see what it’s compared to with others of your gender and grade to arrive at the percentile.</p>
<p>It definitely does. I remember that the Princeton Review book had a chart and I remember comparing 11th and 10th grade and found that someone with the same score would get a lower percentile if applying as an 10th grader than an 11th! I also remember that boys had lower math percentiles than girls for the same score and vica versa with English. </p>
<p>But if you mean like this: </p>
<p>Math: 92% / 83%
Verbal: 77% / 94%
Reading : 84% / 81%
Overall: 89% / 89%</p>
<p>That can probably happen as well 'cause the over-all score isn’t the average of your other percentiles but the percentile calculated from your over-all score.</p>
