The Google Classroom integration requires us to ask for it. The permission is only necessary if you are creating the Google Classroom assignment within TeacherMade so that you can push scores directly to your assignment. This is standard practice; allowing these permissions gives TeacherMade access to your Google classes and students so we can create the assignment and push grades back to Google Classroom.

If you continue to use the TeacherMade option for assigning worksheets with a link, you will not need to allow these permissions.
