How does a weighted grade work?

Each assignment contributes to your final grade proportional to its weight. A midterm worth 30% counts three times as much as a homework worth 10%. Multiply each score percentage by its weight, sum them up, and divide by the total weight.

What letter grade is a 75%?

By standard US grading: 90–100 = A, 80–89 = B, 70–79 = C, 60–69 = D, below 60 = F. A 75% is a C. Exact cutoffs vary by institution.

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

The calculator still works — it divides each weighted score by the total weight, so non-100% weights are normalized automatically. A warning is shown if weights don't sum to exactly 100.

What GPA does an 85% correspond to?

An 85% is typically a B, corresponding to a 3.0 GPA on a 4.0 scale. Use the GPA calculator on Kalkmate for a full GPA calculation with multiple courses.
