Quick Answer
To calculate weighted grades: multiply each grade by its weight percentage, then sum. Formula: (Grade1 x Weight1) + (Grade2 x Weight2) + ... For example, if homework (20%) is 85 and exams (80%) are 90: (85 x 0.20) + (90 x 0.80) = 17 + 72 = 89% overall. To find the final exam score needed: (Target Grade - Current Weighted Grade) / Final Exam Weight.
Key Facts
- Weighted Average = Sum of (Grade x Weight) for all categories
- Common weights: Tests 40-60%, Homework 10-20%, Projects 15-25%, Participation 5-10%
- Letter grades: A = 90-100%, B = 80-89%, C = 70-79%, D = 60-69%, F = below 60%
- Some schools use plus/minus: A+ = 97-100, A = 93-96, A- = 90-92
- Final exam weight is typically 15-30% of total grade
- Extra credit can sometimes push grades above 100%
- Drop lowest score policies exclude your worst grade from calculation
- Curved grades are adjusted based on class performance
Frequently Asked Questions
For weighted grades, multiply each assignment percentage by its weight, sum all weighted scores, then divide by total weight. Example: Test (40%) = 85%, Homework (30%) = 90%, Final (30%) = 80%. Grade = (85×40 + 90×30 + 80×30) ÷ 100 = 85%.
Use this formula: Needed = (Desired Grade - Current × Weight Earned) ÷ Final Weight. For example, if you have 85% on 70% of the course and want 90%, you need: (90 - 85×0.7) ÷ 0.3 = 101.7%. Sometimes the desired grade isn't achievable.
Unweighted (point-based): All points count equally. 90/100 on a test and 9/10 on homework both contribute the same per point. Weighted: Categories have different importance. A test worth 50% affects your grade more than homework worth 10%.
Standard grading scale: A = 90-100%, B = 80-89%, C = 70-79%, D = 60-69%, F = below 60%. Some schools use plus/minus grades (A+, A, A-). Cutoffs may vary by institution - check your syllabus.
Yes, if your teacher allows it. Extra credit adds points beyond the maximum possible. A grade over 100% is possible but may be capped. This calculator shows the raw percentage including any extra credit.
