It can be difficult to understand how grades are calculated when your teacher uses weighted grading. At times, weighted grading seems counter-intuitive. To help, we have posted a help page explaining how weighted grades are calculated. The link to the article is at Weighting Explained.
Quite often there are queries from parents who say, my student did some additional work which gave extra credit but their grade went down.
Extra credit does not always raise the student's grade. Adding a new extra credit assignment will change the total points possible in the extra credit category and could lower the student’s percentage in that category.
Example: The extra credit category is set to give a student a 5% boost in their grade. So far the student has scored 10/10 on the one extra credit assignment, giving them 100% in the extra credit category, and therefore boosting their grade the full 5%. Now you assign another extra credit assignment worth 20 points and the student earns 5/20. The total for the extra credit category is now 15/30 or 50%. The boost has now gone down to 2.5%.
