Course Grade Calculator
Your Final Course Grade

Understanding Your Course Grade Calculation
This calculator helps you determine your final grade in a course based on the weighted scores of different components like assignments, midterms, and final exams. Understanding how your grade is calculated is crucial for academic success, allowing you to identify areas where you excel and areas that may need more attention.
The Math Behind the Calculation
The final grade is calculated using a weighted average. Each component of your course (e.g., assignments, exams) has a specific weight assigned to it, representing its contribution to the overall grade. The score you achieve in each component is then multiplied by its weight. Finally, all these weighted scores are summed up to give you your final percentage grade.
The formula used is:
Final Grade (%) = (Assignment Score * Assignment Weight) + (Midterm Score * Midterm Weight) + (Final Exam Score * Final Exam Weight) + …
It's important that the sum of all weights equals 100%. If the weights do not add up to 100%, the calculator will normalize them or indicate an error, depending on the implementation. This calculator assumes weights are provided as percentages (e.g., 30 for 30%).
How to Use This Calculator
- Enter Component Weights: Input the percentage weight for each graded component (Assignments, Midterm Exam, Final Exam, etc.). Ensure these weights sum up to 100%.
- Enter Your Scores: For each component, enter the percentage score you have achieved.
- Calculate: Click the "Calculate Final Grade" button.
- View Result: The calculator will display your final course grade as a percentage.
Example Calculation
Let's say a course has the following structure:
- Assignments: 30% weight, you scored 85%
- Midterm Exam: 30% weight, you scored 78%
- Final Exam: 40% weight, you scored 92%
The calculation would be:
Final Grade = (85 * 0.30) + (78 * 0.30) + (92 * 0.40)
Final Grade = 25.5 + 23.4 + 36.8
Final Grade = 85.7%
This tool is invaluable for students to track their progress, understand grading policies, and make informed decisions about their study efforts throughout the academic term.

var weightedMidterm = (midtermScore / 100) * midtermWeight;

} else {
document.getElementById("finalGrade").innerHTML = "Error";
