Weighted grades assign different importance to assignments. Finals might count 40% while homework counts 20%.
Standard scale: A (90-100%), B (80-89%), C (70-79%), D (60-69%), F (below 60%).
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.
For unweighted grades:
Grade = (Sum of Scores / Sum of Max Scores) × 100For weighted grades:
Grade = Σ(Score/Max × Weight) / Total WeightExample with weights:
(85/100×30% + 90/100×70%) = 88.5%The 4.0 GPA scale is the most common grading system in the United States.
