Earned points. Possible points. Your overall percentage.

90 / 100 points
How points-based grades work
Add earned points, divide by all possible points, and multiply by 100. The example above combines 18/20 and 72/80 into 90/100 = 90%. Extra credit can produce a percentage above 100%. This is not a category-weighted average; use the weighted calculator if your syllabus specifies category weights. Letter grades use our example scale, not your school's official policy.
