In some schools, primarily public high schools, weighted-grade systems give students a numerical advantage for grades earned in higher-level courses or more challenging learning experiences, such as honors courses, Advanced Placement courses, or International Baccalaureate courses.
The student has earned the following scores for each category: tests-83, final exam-75, quizzes-90, homework-100. We need to calculate the student's overall grade. To calculate a weighted average with percentages, each category value must first be multiplied by its percentage.Then all of these new values must be added together. In this example, we must multiply the student's average on all tests (83) by the % that the tests are worth toward the final grade (40%).xamples: Weighted Average with Percentages. Example 1: A student is enrolled in a biology course where the final grade is determined based on the following categories: tests 40%, final exam 25%, quizzes 25%, and homework 10%.
