Understanding Grade Calculations
Weighted vs Unweighted Grades
Weighted grades assign different importance to assignments. Finals might count 40% while homework counts 20%.
Letter Grade Scale
Standard scale: A (90-100%), B (80-89%), C (70-79%), D (60-69%), F (below 60%).
GPA Conversion
Letter grades convert to GPA: A=4.0, B=3.0, C=2.0, D=1.0, F=0.0 on a 4.0 scale.
Grade Calculation Formulas
Simple Average Formula
For unweighted grades:
Grade = (Sum of Scores / Sum of Max Scores) × 100Weighted Average Formula
For weighted grades:
Grade = Σ(Score/Max × Weight) / Total WeightFinal Grade Calculation
Example with weights:
(85/100×30% + 90/100×70%) = 88.5%Common Grading Systems
