How do I remaster grade passback and re-sync my entire Canvas course gradebook to SchoolTool as an instructor?
As an instructor, you can re-sync your entire Canvas gradebook to your SIS in the Grade Sync page. Remastering grade passback for your course re-syncs your Canvas course gradebook to your SIS gradebook.
