What does "top 10% of graduating class" really mean?

<p>Since everybody in this forum seems to know what they are talking about, I’ll ask my question.
I’m a Junior at a small (26 kids in my class) Catholic high school in West Virginia. I have 3.88 GPA (i had my b’s in junior high and 9th grade) and am ranked 5th in my class behind four 4.0 students. However, i have the hardest schedule in my high school because i have twice as many AP’s as any other student ini my grade and have doubled up english, science, and math classes throughout high school. Additionally, I have an SAT score of 2100 and an ACT of 31. When I see the top ten percent statistics i get worried that my lack of focus in 8th and 9th grade will kill my chances at getting into schools like Middlebury and Wesleyan. I know for a fact that if i transfered to the public high school i would be in the top 10%, but i have no desire to do so. Will not being ranked in the top 10% really kill my chances of getting into the schools i want?</p>
