How a weighted grade works

Each category counts for its share of the grade. Multiply each category's grade by its weight, add those up, and divide by the total weight of everything graded so far.

Class grade = Σ (grade × weight) ÷ Σ weight

With homework 92% (20%), quizzes 85% (20%) and tests 78% (40%): 92 × 0.2 + 85 × 0.2 + 78 × 0.4 = 66.6 points out of the 80% graded so far, so your grade is 66.6 ÷ 0.8 = 83.25%, a B. To keep that B with the final worth the last 20%, you need (83 − 66.6) ÷ 0.2 = 82% on it.

Questions

How do I calculate my grade with weights?

Enter each category from your syllabus (homework, quizzes, tests, projects) with your current grade in it and its weight. The calculator multiplies each grade by its weight and adds them up, so a category worth 40% counts twice as much as one worth 20%.

What if my weights don't add up to 100%?

If they add up to less, the calculator treats the missing part as work still to come and shows what you need on it. If they add up to more, it treats them as relative weights: each category counts for its share of the total.

My class uses points, not percentages. Does this work?

Yes. Choose "Points" and enter the points you earned and the points possible for each category. Your grade is total points earned divided by total points possible. Leave "points earned" empty for anything not graded yet.

What grade do I need on the rest of the class?

Leave the grade empty for anything that isn't graded yet, like the final. The calculator shows what you need on the remaining work for an A, B, C, D or a pass, and "Plan my final" opens the final grade calculator with your numbers filled in.

What's the difference between a weighted and an unweighted grade?

An unweighted grade is a plain average: every assignment counts the same. A weighted grade gives each category the share your syllabus sets, so one test can count more than several homework assignments. (A "weighted GPA" is something else: extra points for honors and AP classes.)

Can I enter letter grades?

Yes. A letter counts as the middle of its range on your grading scale, so a B is 85% on the standard scale. Percentages are more accurate if you have them.
