Frequently Asked Questions
What is a weighted grade average?
A weighted grade average applies a weight (percentage) to each category — such as homework at 20%, exams at 50%, and projects at 30% — and calculates the average based on those weights. This reflects the actual importance of each component rather than treating all assignments equally.
What grading scale does this calculator use?
This calculator uses the standard 4.0 scale: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, F = 0.0. Letter grades are converted to grade points, multiplied by credit hours, summed, and divided by total credit hours.
How is weighted average different from simple average?
A simple average adds all your grades and divides by the number of grades. A weighted average multiplies each grade by its weight before summing. For example, if homework (worth 10%) is 100% and exams (worth 90%) are 70%, a simple average would incorrectly show 85% — but the weighted average of 73% is accurate.
Can I calculate GPA with this?
This calculator is designed for individual course grading. For overall GPA across multiple courses, you need a dedicated GPA calculator that accounts for all courses and their credit hours together. This calculator works best for seeing where you stand in a single course.
