How do I calculate my weighted course grade?

Multiply your average in each category by its weight and add the results. If homework (20%) averages 95, exams (50%) average 82, and projects (30%) average 88, your grade is 0.20×95 + 0.50×82 + 0.30×88 = 86.4%.

What score do I need on the final exam to reach my target grade?

Use: needed score = (target − current grade × (1 − final weight)) ÷ final weight. With a 85% current grade, a 20% final, and a 90% target: (90 − 85×0.8) ÷ 0.2 = 110% — meaning the target isn't reachable and you'd need to adjust expectations.

What's the difference between points-based and percentage-based grading?

In points-based grading, every assignment contributes its raw points to one pool, so a 100-point exam matters 10× more than a 10-point quiz. In weighted (percentage) grading, categories have fixed shares regardless of point totals. Check your syllabus to know which your course uses.

What letter grade is a given percentage?

A common US scale is A: 90-100%, B: 80-89%, C: 70-79%, D: 60-69%, F: below 60%, often with +/− cutoffs at the 3s and 7s. Cutoffs vary by school and instructor, so always confirm with the course syllabus.

How do dropped assignments affect my grade?

When an instructor drops your lowest quiz or homework score, your category average is computed without it, which usually raises the average. Recalculate by excluding the lowest score from that category before applying the category weight.

How it works

A grade calculator finds your overall grade by weighting each component (tests, homework, projects) by its share of the final grade. Multiply each score by its weight, add them up, and divide by the total weight.

Weighted grade

Final = Σ (score × weight) ÷ Σ weights

score: grade on each component (%)
weight: how much that component counts

Worked example

Tests 90% (weight 50%)
Homework 80% (weight 20%)
Final exam 85% (weight 30%)

(90×0.5) + (80×0.2) + (85×0.3)
= 45 + 16 + 25.5

Final grade = 86.5%.

Good to know

Weights should sum to 100% (or 1.0); otherwise divide by the total weight you have.
To find the score needed on a final, solve for the missing component given your target.
Dropping a low score, if the syllabus allows it, can meaningfully raise the weighted total.
