This is a Google Sheet you can use to apply a linear curve to student grades. The curve is larger for lower grades, and smaller for higher grades. A 20 will adjust to a 40, a 60 to a 70, and a 90 to a 93 (rounded). To score student grades with the curve, copy and paste the class period, first name, last name, and percent score into the appropriate column. The curve is set to adjust scores falling between 20 and 100 to a range from 40 to 100. Scores below 20 will adjust by up to 25 points.
