<p>Generally speaking, those who take SATII's are students who score in the top 50% on standardized tests, and who are aiming for somewhat selective colleges. Therefore, percentiles are very innaccurate, because you're not being compared to all students but only a small, selective portion. My SAT II's had crazy percentiles too: </p>
<p>But then I found out that so many people get 800's on these tests that an 800 isn't even the 99th percentile. So with that in mind, you really don't need to worry about the percentile as much as you need to worry about obtaining a high score.</p>
