What is the standard grading scale?

The most common U.S. scale: A = 90-100% (4.0), B = 80-89% (3.0), C = 70-79% (2.0), D = 60-69% (1.0), F = below 60% (0.0). Plus/minus variants adjust by 0.3 (e.g., B+ = 3.3, B- = 2.7).

How do I calculate my grade with extra credit?

Add extra credit points to your earned points before dividing by total possible. For example, 45 earned + 3 extra credit = 48 out of 50 = 96%.

What This Calculator Does

This exam score calculator converts raw exam scores into percentages, letter grades, and GPA equivalents. It supports both simple scoring (points earned out of total) and multi-section exams with different weights.

The Formula

Percentage = (Points Earned / Total Points) x 100 | Weighted Score = Sum of (Section Score x Section Weight)

For simple exams, divide points earned by total possible points and multiply by 100. For multi-section exams, each section percentage is multiplied by its weight, then summed for the overall score. Letter grades follow the standard scale: A (90-100), B (80-89), C (70-79), D (60-69), F (below 60).

Step-by-Step Example

Enter exam scores

For a simple exam: 42 points earned out of 50 total points.

Calculate percentage

42 / 50 x 100 = 84%. This is a B grade (3.0 GPA equivalent).

Multi-section example

Multiple choice (40% weight): 85%. Short answer (30% weight): 78%. Essay (30% weight): 90%.

Calculate weighted score

(85 x 0.40) + (78 x 0.30) + (90 x 0.30) = 34 + 23.4 + 27 = 84.4%. Letter grade: B.

Common Mistakes to Avoid

Assuming all sections carry equal weight. Always check if the exam uses weighted sections before calculating your overall score.
Forgetting to account for extra credit points that may push the total above the base maximum.
Using the wrong grading scale. Some professors use modified scales (e.g., 93+ for an A instead of 90+). Check your syllabus.
Not accounting for curve adjustments that the professor may apply after grading.
