how do i submit new assignment if wrong one was sent?
Answer
Multiple Attempts
The number of submissions and the ability to re-submit an assignment is controlled by the Instructor of a class. If the assignment is set to allow re-submissions, then when you go back to the assignment, a button will appear near the bottom of the screen labeled "Start New Submission".
Clear Attempt
If that button is not available you will need to ask your Instructor to clear your attempt.
