About Grade Curve Methods

Curve Methods:

  • Linear Scale: Proportionally scales all grades to reach maximum
  • Square Root: Benefits lower grades more than higher ones
  • Additive: Adds fixed points to every grade

Advanced Methods:

  • Bell Curve: Redistributes grades to target mean with standard deviation
  • Percentile: Reassigns grades based on class ranking percentiles
  • All methods respect maximum grade limits and prevent negative scores
