Centrally setup student accounts with a spreadsheet of email addresses and names (and ideally student IDs)
This would save the students time and allow us to get started faster. As an instructor, I upload a spreadsheet of email addresses and associate them with the license code i have paid for. This then causes the students on the list to receive an email containing an invite link.
It would also mean that each of the student's accounts is set up in the same way, which makes the results spreadsheet easier to manage.
