Grade passback and grading windows

Community Member

We use IC for our SIS. The grading window for teachers to post quarter and semester grades is only open for a couple days.  Then, after the term has ended, we may re-open the grading window to post revisions to "incomplete" grades. Does anybody know if the grades posted to a Q1 assignment will sync to IC and affect the Q1 grade after Q1 is over?

Thanks for any information you have
