Yes, you will have to use gradebook to enter PBL scores. Sorry!
Also understand the point of this is for you to NOT enter scores or assignments twice!
- Posting of Midterms and final grades
So right now you do not need to even log in to it. All your assignments are and should be completed in Canvas. And Canvas only. Assignments will push to Gradebook. I have always had people ask about assignments that are not completed "electronically" or in Canvas. Not a problem. Put scores in Canvas - Stay out of Gradebook!
