Class rank percentile = (class_size - rank) / class_size * 100. If you are ranked 15th in a class of 350, your percentile is (350 - 15) / 350 * 100 = 95.71%. This means you performed better than 95.71% of your class.
- Formula: (class_size - rank) / class_size * 100
- Rank 1 = highest percentile (valedictorian)
- Percentile shows what % of students you outperformed
- Top 10% = 90th percentile or higher
- Top 25% = 75th percentile or higher (first quartile)
