I use the same grading policy across all my classes.
AP US History, Economics, & Psychology
Grades are calculated through a total points system. Each assignment is worth a certain number of points. For example, a Classwork Practice Essay may be worth 10 points, homework worth 6 points, and quizzes/tests with a higher point value may add up to a total number of points based on the number of questions and tasks (written responses/essays), etc. The earned points possible are divided by the total points possible to get an average. Example, 200 points earned out of a total possible amount of 250 points equals an 80 average. You want to earn as many points as possible.
