See what a curve does to your raw exam score using the three methods instructors most often apply. A flat curve simply adds a fixed number of points to everyone. A top score curve scales grades so the highest score in the class becomes one hundred and every other score rises by the same factor. A square root curve takes the square root of your percentage and multiplies by ten, which lifts lower scores more than higher ones. Enter your raw percentage and the parameter each method needs, and the tool shows the curved result, capped at one hundred where appropriate. Everything runs in your browser with no data leaving your device. Use it to estimate your grade after a hard test, to compare how different curving policies would treat your score, or to understand a curve your professor announced.
