I was reviewing the Google Classroom API and noticed there was not an option for getting grades. I need to extract the assignment grades from Google Classroom into an external grade book app that I am creating. Does anyone know if this is possible, or how to do this?
You can definitely get grades from the API.
Classroom.Courses.CourseWork.StudentSubmissions.list(course.id, work.id).studentSubmissions
From there, loop through the studentSubmissions: studentSubmissions[i].assignedGrade
That gets the assigned grade for that specific assignment. I also grab studentSubmissions.userId in order to get the student name. Let me know if you need anything else.
