This happens when the Max Extra Credit is not increased, and an assignment is added to the extra credit category.
Extra credit does not always raise the student's grade. When a new extra credit assignment is added to the category, the total points distribution can lower the student’s percentage in that category.
For example, the Extra Credit category is set with 5% Max Extra Credit. This means that the whole category will give each student a 5% boost in their grade. If Paul, a student scored 10/10 in the first extra credit assignment, it gives him 100% in the extra credit category, boosting his grade by a full 5%.
However, when the teacher assigns a new Extra Credit assignment worth 20 points and paul only earns 5/20 in it. The total for the extra credit category for Paul now becomes 15/30 or 50%. Hence reducing the grade and boosting it by only 2.5%.
Note: Students or parents may use the Weighting Grade Calculator to assess their grade when weighting is applied.
