Frequently Asked Questions

How is the weighted grade calculated?

Each assignment's percentage score (score/total) is multiplied by its weight. The weighted scores are summed to get your final grade. For example, a 90% on a 20% weighted assignment contributes 18% to your final grade.

What letter grade scale is used?

The calculator uses a standard scale: 97-100% (A+), 93-96% (A), 90-92% (A-), 87-89% (B+), 83-86% (B), 80-82% (B-), 77-79% (C+), 73-76% (C), 70-72% (C-), 67-69% (D+), 63-66% (D), 60-62% (D-), below 60% (F).

Do weights need to add up to 100%?

No, the calculator works with any total weight. However, for accurate results, your weights should represent the actual grading breakdown of your course.

Can I calculate what grade I need on a final exam?

This calculator shows your current grade based on completed assignments. To calculate what you need on a final exam, add your current assignments and the final exam as a separate row with the desired total.
