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.
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%).owever, this only works when all the items are weighted equally. For example, to calculate your average monthly electricity bill for a year, it would make sense to add up the billed amounts for the previous twelve months and divide by twelve since each bill cycle is roughly the same period of time (one month).
