Type your test scores to see your average and letter grade. Choose Percent if your scores look like 85 or 92%, or Points if they look like 18/20 — tap an “All tests out of” button to fill in the total for every row at once. If some tests count more than others (say the final is worth 30%), switch to Weighted and add each weight; a row can also be a whole category, like a homework average. Empty rows are skipped, and you can add as many tests as you need. Pick your school’s grading scale to see the letter, GPA points, and how far you are from the next grade up.
How it works: In percent mode every test counts the same: average = sum of scores ÷ number of tests. In points mode your grade is total points earned ÷ total points possible × 100, so a 100-point test counts five times as much as a 20-point quiz. With weights, each test’s percent is multiplied by its weight and the total is divided by the sum of the weights — so if the weights only add up to 70%, you see your grade on the work graded so far. Check your syllabus for the exact scale your teacher uses.
