Hi @CGME,

I have some perhaps bad, but also good news for you around this.  I'll start with the perhaps bad...  In Canvas, every assignment really belongs to an assignment group (even if there is just a single "assignments" group with everything in it).  I don't know of a way around that, though you could move all of your assignments into a single group and remove the others.

Now for the good news!  Even if you keep your assignment groups, you can hide them from the gradebook.  The "View Gradebook View Options" section of the  How do I use the Gradebook? - Instructure Community  guide shows the checkbox to "Hide Assignment Group Totals," which should effectively do what I believe you want.

I hope this helps!
