We have several courses where students may complete assignments at any point during the semester. The grades are recorded in another system and exported in a Canvas-compatible CSV file. The idea was that we'd just upload the grades periodically so students can track how they're doing in Canvas.
However, if I upload the grades for September, and then go back and try to upload the grades for October, Canvas tries to overwrite the September grades with zeros. Is there any way around this? Here's what I've tried:
- Change the zeros on the CSV to null values. Canvas tries to change grades to nulls.
- Just re-upload all the data from both Sept. and Oct. This *could* work, but it would overwrite any hand-entered exceptions in Canvas. Those would be highlighted if they went down (but not if they went up).
