To do this you first need to log on to your Blackboard course, and click on the Grade Center under Evaluation in the lower left of the screen.
On the Grade Center screen, find the Running Weighed Total column, click on the gray arrow button, and select Edit Column Information option.
On the Edit Column Information page, change these information if you want.
Then, scroll down and find the third section. Use the forward and backward arrows in the middle to select the columns (items) and categories.
Once you made the selection, the columns and categories will be shown in the Selected Columns, and you need to enter the weight for each item. Percentages should add up to 100 percent.
Set the Options.
Click on the Submit button to finish.
