You still can change task or quiz that you have made on Eliademy after at least one submission is received from your students. There are some limitations::
In both cases changing the due date is possible at any point.
- For quizzes - as an instructor you can NOT add additional questions, but modify existing ones if you found a typo. Also deleting existing questions is not possible.
- For assignment - an instructor can modify tasks but will see a warning message that students have to be explicitly notified about changes
