percentile

<p>do you know what the percentile is based on ? on raw score, or scaled score ?
I think it is based on raw score... but I have received the score report, and the table "Percentiles and Average Scores" shows a fixed percentile number for each score level.</p>

<p>for example: Oct 2007
Literature 800-99
Chemistry 800-95
Physics 800-92
US History 800-99
World History 800-97
Math I 800-99
Math II 800-91
Bio E 800-99
Bio M 800-98
......</p>

<p>Did anyone got 800 in these tests with higher percentile ???</p>

<p>Percentiles are based on scaled score. Everyone who gets the score of 800 in any particular subject receives the same percentiles. I received physics chemistry and mathematics II received scores of 800 and got the percentiles you have stated.</p>
