Implementation Guide
This Excel tool standardizes exam scores on a 0–100 scale using a linear normalization formula and applies a curve to boost low scores (10 points for scores under 60, 5 points for 60–69). The MIN and MAX functions calculate the range of raw scores, while the standardization formula scales each score to the 0–100 range for fair comparison across classes. The nested IF function applies the curve to ensure no student fails due to a difficult exam. It tracks 100+ student scores, integrates with exam grading sheets, and uses conditional formatting to highlight curved scores. Ideal for K-12 and college teachers, it reduces grade curving time by 75% and ensures grading consistency across multiple sections.
