Grade Calculators

Courses are graded one of two ways. Check your syllabus before you start, because the two methods give genuinely different answers from the same work.

Averaging your assignment percentages treats a ten-point quiz as equal to a hundred-point midterm. Almost no course works that way.

In a points course the weighting happens by itself: add up everything you earned, divide by everything available, and a big assignment counts for more because it carries more points.

In a weighted course the syllabus fixes each category's share regardless of how many points are in it — twenty homework assignments might still be worth only 15% between them.

The most common question in this category, and the arithmetic is simpler than it looks. If the final is worth 20%, everything before it is worth 80%.

With an 88% going in, a 90% target and a final worth 20%, you need a 98%. The Final Grade Calculator works that out both directions and says plainly when a target has become unreachable — which is better known before the exam than after.

• If your lowest quiz is dropped, leave it out rather than entering it.
• Curves are applied after this arithmetic and vary by instructor.
• Some instructors round 89.5% up to an A-; others do not round at all.
• Extra credit can push a grade above 100%, and none of these tools caps it.
