Before diving into the calculation, it's crucial to understand the grading system your instructor uses. Two common systems are:
- Points-Based System: Each assignment, quiz, and exam is worth a specific number of points. Your final grade is determined by the total points you earn divided by the total possible points.
- Weighted System: Different categories (e.g., homework, quizzes, exams, final exam) are assigned different percentage weights. The final grade is calculated by multiplying your grade in each category by its weight and then summing the results.
Calculating Final Percentage in a Points-Based System
- Determine Total Points Earned: Add up all the points you've earned on assignments, quizzes, and exams.
- Determine Total Points Possible: Add up the maximum points possible for all graded items.
- Calculate the Percentage: Divide the total points earned by the total points possible and multiply by 100.
Example:
Let's say your history class has the following grading breakdown:
- Quizzes: 100 points total
- Midterm Exam: 150 points
- Final Exam: 200 points
- Assignments: 50 points
Total points possible: 50 + 100 + 150 + 200 = 500 points
If you earned the following scores:
- Quizzes: 85 points
- Midterm Exam: 120 points
- Final Exam: 170 points
- Assignments: 40 points
Total points earned: 40 + 85 + 120 + 170 = 415 points
Final Percentage: (415 / 500) * 100 = 83%
Therefore, your final grade in the class is 83%.
Simplify this process with our percentage calculator! Just enter your total points earned and the total possible points to instantly find your percentage.
Calculating Final Percentage in a Weighted System
- Determine Category Weights: Identify the percentage weight assigned to each category (e.g., homework, quizzes, exams).
- Calculate Category Averages: Calculate your average percentage grade in each category.
- Multiply and Sum: Multiply each category average by its corresponding weight (as a decimal) and then sum the results.
Example:
Suppose your math class has the following weights:
- Homework: 20%
- Quizzes: 30%
- Exams: 50%
And your average grades in each category are:
- Homework: 90%
- Quizzes: 80%
- Exams: 75%
Final Percentage: (0.20 * 90) + (0.30 * 80) + (0.50 * 75) = 18 + 24 + 37.5 = 79.5%
Therefore, your final grade in the class is 79.5%
