How to Calculate Weighted Class Grades
- 1). Determine your grade on each assignment and the weight of the grade. For example, assume you receive an 85 percent on a project that counts for 20 percent of your final grade and you receive a 100 on a test that is 80 percent of your grade.
- 2). Multiply the grade on the assignment by the grade weight. In the example, 85 times 20 percent equals 17 and 100 times 80 percent equals 80.
- 3). Add together all your weighted grades to find your overall grade. In the example, 17 points plus 80 points equals a weighted grade of 97.
