Thanks for the reply. I unfortunately don't have the time to create a non-terms grade book as I am entering my final marks. I was able to delete the multiple columns and import only one instance of the assignment. I feel as though if I do another import it will double up again for whatever reason. Also to note, the [[ungraded]] feature was not working with this assignment for some reason. Thank you.

HI, I am looking for clarification on the add-ons being offered. I currently have a subscription to the Google grades Sheets add-on. However, I see the Grade reports for Google classroom add-on now. I am looking for a solution to have grades calculated in Google classroom. Students are wanting to know their calculated grades all the time with in the classroom. Is there a product that offers this? I am finding the import process into Google sheets slow and then I need to email students which is very slow as well. An "all in one solution" with in Google classroom is what I am after. Thank you
