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.
Examples: 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%.he 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.
