Frequently asked questions
- What is the difference between percentile and top percentage?
- Top percentage is simply rank ÷ class size (e.g. top 5%). The percentile rates you against classmates so the top student is the 100th percentile; the two are related but framed oppositely.
- Why divide by class size minus one for the percentile?
- Using (size − 1) places the top student at exactly the 100th percentile and the last at the 0th, spreading ranks evenly across the full 0–100 range.
- My school uses deciles — can I still use this?
- Yes. Enter your numeric rank and class size to get an exact percentile; you can then map it to a decile (top 10% = first decile, and so on).
