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

<p>At S1 & S2’s school there is a rank provided, but a document goes with the transcript that says that there is no weighting and a student who has no honors or AP courses can be more highly ranked than one who had 8 or 9 APs. The counselors write that the schools should ignore the rankings. Must be working, kids who are ranked 185/405 are getting into top 10 schools.</p>
