Adding your own columns. There are three types of columns you can add:
Manual columns that you can use to manually record grades for assessments or activities that are outside of your MyLab course, such as class participation.
Calculated columns that take the scores from other columns and calculate the average score, the total score, or identify the highest score. Calculated columns are useful for getting an average for all assignments.
Weighted columns that weight the grades for columns that you select.
Note: You can delete columns that you have added and edit the column definitions. You can also enter and edit scores for manual columns.
