Hello Janet,
Thank you for reaching out to the academic advisors. You may save your assignment the way you deem it necessary to find the file within your folder. If there are no specific instructions on methods of saving your assignment, then choosing the method best for you is completely acceptable.
The activity should be indicated within the course workspace under that specific course. Simply choose the lesson within the assignments tab that indicates that particular discussion question.
If you have any other questions, please feel free to contact us for further clarity. Have a great day and happy learning.
