Importing a course that exists will match it with the first course that it finds that matches

[bledsoef]

When you go to Import Course Participants on Course Management, courses that exist in the spreadsheet you upload try to match to existing ones so there are not duplicate courses. However, when we import a course and that course exists in multiple terms, it will always match to the first one. This is not always the correct course.

We need to figure out what the best matching technique should be if the course already exists. I think we should rework this function so that it prioritizes the current term over previous terms.
