So, in "No Categories" mode, we might create the following gradebook:

• My Default Gradebook
  • Item 1 (25 points)
  • Item 2 (25 points)
  • Item 3 (25 points)
  • Item 4 (25 points)
  • Extra Credit Item (10 points)

This gradebook would have a total possible non-extra-credit point value of 100, with 10 extra credit points possible.

...

In "Categories" mode, calculations are still point-based, and work along the same fundamental principle, though when it comes to extra credit there is a further complication. By organizing the points into categories, we end up with the idea of an item that contributes extra credit to that category specifically, where it doesn't make sense to determine the category contribution to the overall score unless at least one non-extra-credit item has been graded for that category.

• My Default Gradebook
  • Category 1
    • Item 1 (25 points)
    • Item 2 (25 points)
    • Item 3 (25 points)
    • Item 4 (25 points)
    • Extra Credit Item (10 points)

So under this case, we have the same basic calculation as above, but if we add a student who only completed the extra credit item, we get another non-intuitive case:

Weight Based Calculations

• My Default Gradebook
  • Category 1 (60% of course grade)
    • Item 1.1 (25 points) (25% of category, 15% of gradebook)
    • Item 1.2 (25 points) (25% of category, 15% of gradebook)
    • Item 1.3 (25 points) (25% of category, 15% of gradebook)
    • Item 1.4 (25 points) (25% of category, 15% of gradebook)
    • Extra Credit Item (10 points) (10% of category, 6% of gradebook)
  • Category 2 (40% of course grade)
    • Item 2.1 (15 points) (40% of category, 16% of gradebook)
    • Item 2.2 (15 points) (30% of category, 12% of gradebook)
    • Item 2.3 (15 points) (30% of category, 12% of gradebook)

Weight based calculations are used whenever a gradebook is in "Weighted Categories" mode. In this
case the instructor must lay out the desired weighting of each category and each item within those categories.

Note that, taking each student above individually, the hyphens above could be the result of any of the following:

• Dropping the lowest score in a category
• Excusing that student from that one item in that category
• Choosing not to enter a grade for that student for that item
