How we calculate the grade average

Weighted average = Σ(grade_i × weight_i) / Σ(weight_i). Arithmetic average = Σ(grade_i) / n. Weights allow important grades (e.g. exams) to count more than minor ones (e.g. quizzes).

Example grade average calculation

Grades: 5 (weight 2), 4 (weight 1), 3 (weight 1), 5 (weight 2), 4 (weight 1). Weighted average = (5×2 + 4×1 + 3×1 + 5×2 + 4×1) / (2+1+1+2+1) = 31 / 7 ≈ 4.43. Arithmetic average = (5+4+3+5+4) / 5 = 4.20.
