Force a gradebook to be out of 100 with extra credit

Now after switching we need to fix the weights. We will begin by switching all of our categories to a simple weighted mean of grades done the same way as before but for the rest of the categories. Then just alter the total points for each category to be the weights of the categories instead. The weight of the category of participation is now 20 instead of 10 because the attendance is worth 20 points. We do still want these weights to be out of 100.

Here are the original weights used if you need them: 

• Participation - 10%
• Weekly Assignments - 25%
• Quizzes - 15%
• Midterm and Final - 50%
