Grade Calculator

To calculate your grade: (1) For weighted classes, multiply each assignment score percentage by its category weight percentage, then sum all results. (2) For points-based classes, divide total points earned by total possible points and multiply by 100.

70% of your grade represents the weight contributed by a specific assessment category (such as midterms or coursework). To find your earned points from a 70% weight, multiply your category average percentage by 0.70. For instance, scoring 85% on a 70% weighted component contributes 59.5 percentage points to your overall course grade.

To convert a raw fraction score (like 15/20) into a percentage, divide the numerator by the denominator and multiply by 100 (15 ÷ 20 × 100 = 75%). To convert percentages into letter grades or a 4.0 GPA scale, reference standard conversion tables (90-100% = 4.0 / A, 80-89% = 3.0 / B).

A 15/20 grade equals 75% (15 ÷ 20 = 0.75 = 75%). On standard letter grade scales, 75% translates to a grade of C+ or B-.

The weighted grade formula is: Overall Grade = (Score 1 × Weight 1) + (Score 2 × Weight 2) + ... + (Score N × Weight N). The final exam target formula is: Needed Score = [ Target Final Grade - (Current Grade × (1 - Final Exam Weight)) ] ÷ Final Exam Weight.

To convert marks to grade points on a 4.0 scale: (1) 90–100% = 4.0 (A), (2) 80–89% = 3.0 (B), (3) 70–79% = 2.0 (C), (4) 60–69% = 1.0 (D), and (5) Below 60% = 0.0 (F).
