Gradescope is something Drexel CCI officially supports.
There is now integration of Gradescope into Bb Learn. We can assist with that if you email firstname.lastname@example.org .
So you create assignments in Gradescope, upload a list of students and their email addressed, which you can get from the “Work Offline” > “Download” functions in Bb Learn.
You can opt for students to be invited. They get an email, click a link in an email, and register. Then they have access to your course in Gradescope.
You might want to run through “Manage a Course Roster” and “Create an online assignment” at the webpages below, or any other videos you wish. Both links actually go to the same webpage.
