Curious about this.

Normally, I can do it by increasing the overall weight of the column, but usually the course must have a specific number of points allocated to it.

Any tips?

John,

Do you just want to add extra credit points to a weighted column? If so, I've written a blog post about this.

This works great as long as you have every column in the weighted total worth 100%. If you don't (and I've had faculty who don't), this will change the value based on the total points of the weighted grade (I'm not sure how this is calculated).

Right you are Will.

What I've found is this:

If you have a course with 4 assignments and 2 exams.

A1 - 20 pts

A2 - 10 pts

A3 - 10 pts

A4 - 25 pts

E1 - 100 pts

E2 - 100 pts

Then the weighted column is as such:

Assignments = 20%, weighted proportionally

Exams = 80%, weighted proportionally or equally does not matter in this scenario.

What you'll get is this:

4x assignments.

Total = 65 points / 4 = 16.25

2x exams

Total = 200 points / 2 = 100

20% of 16.25 = 3.25

80% of 100 = 80

80+3.25 =

83.25 / Total.

This is how Blackboard figures out the weighted columns, as far as I can tell.

So that said, when calculating extra credit in this scenario, you run into some mathematical errors.
