Calculate your overall course grade when different components count for different shares of the total. Enter each item, such as homework, quizzes, a midterm and a final, along with the score you got and the weight that piece carries, and the calculator produces a proper weighted average rather than a plain mean. It multiplies each score by its weight, adds them up, and divides by the total weight you entered, so it works whether your weights add up to a hundred or not. This is the correct way to track where you stand in a class and to see how much a strong or weak result on one component moves your final mark. Add as many rows as you need. Everything is computed locally in your browser.
