Understanding the 10 * √x Formula

The core of our 100% free calculator is the mathematical principle of non-linear scaling. When you apply the square root curve (also known as the "standard curve"), you are normalizing performance based on a root-function. This means that a student with a score of 36% gets their grade lifted to 60%, while a student with 81% moves up to 90%.
