Is there a way to calculate a weighted average grade for first and revised drafts, say for example in a composition course? Here's the scenario: a student turns in a paper, then decides to submit a revision after receiving feedback. The instructor grades both papers. The "final" grade will then be calculated as such: 30% from the first draft, and 70% from the revised paper.  I was just wondering if there was a way to set this up on gradebook, or if I will have to do this outside of Canvas (say, Excel), then enter the scores manually.
