Frequently Asked Questions
How does weighted grade calculation work?
Weighted grades multiply each assignment grade by its weight, sum all weighted scores, then divide by the total weight. For example, if you have 90% on a 30% weighted exam and 85% on a 70% weighted final, your grade would be (90×0.3 + 85×0.7) ÷ (0.3+0.7) = 86.5%.
Can I use letter grades instead of percentages?
Yes, our calculator supports letter grades from A+ to F. Letter grades are automatically converted to their percentage equivalents (A+ = 97%, A = 93%, A- = 90%, etc.) for calculation purposes.
How accurate is the final exam grade predictor?
The final exam calculator is mathematically precise, using the formula: Required Grade = (Target Grade - Current Grade × (1 - Final Weight)) ÷ Final Weight. It will tell you if your target is achievable or if you've already met your goal.
Can I save and reuse my grade calculations?
Yes, you can save multiple grade calculations with custom names, load them later, and export/import your data in JSON or CSV formats for backup or sharing between devices.
What's the difference between percentage and points weighting?
Percentage weighting means weights must add up to 100% (e.g., midterm 40%, final 60%). Points weighting uses raw point values (e.g., midterm 400 points, final 600 points) where the ratio determines the weight.
