There is no universal gradebook in Classwork.com. To view your student's grades, you navigate to the Assignment Detail Page for individual Assignments. Or you can view the scores for all assignments per student on the "Students" page.

If you use one of our integrations, Google Classroom, Canvas, or Schoology, it is possible for your grades to sync to your gradebook. Otherwise, you will need to manually transfer the grades to your gradebook. You can speed up this process by exporting scores to a CSV File.
