How do you calculate extra credit in a weighted grade format?
1.) Example 1: Add an extra credit grading "group" and give that group a percent of what it is worth. Sample: There are several groups in the gradebook Participation - 20, Discussion - 30, Exams - 50. Your students can earn extra credit completing an additional assignment. The three groups listed prior: Participation, Discussion and Exams all equal 100. You make another assignment group titled Extra Credit and give that group 5%. Now you total grading is out of 105%.
2) Example 2: Add extra credit points to a already existing group, using the same example as above, we have three grading groups: Participation - 10, Discussion 30, Exams - 50. To add extra credit points you would add a assignment within an existing group, let's say Participation, There are 5 assignments in Participation and those 5 assignments equal 10% of the grade. Now you add another assignment to participation labeled Extra Credit.
Which is correct?
Also, should the "treat ungraded assignment as zero" option be checked?
