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’ve posted a help page explaining how weighted grades are calculated.
1. A student received 100% on an assignment and yet their grade went down.
2. A student did some additional extra credit but their grade went down.
1. The student had over 100% in that category, most likely due to extra credit.
Example: A student has turned in all of their homework and has some extra credit points, putting their average for the category at 110%. If the student receives a 100% on their next graded assignment, their weighted average for the Homework category will go down because 100% is less than 110%.
2. 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. Her total for the extra credit category is now 15/30 or 50%. Her boost has now gone down to 2.5%.
The student understands the grading system.
