Creating AutoGrade assignments looks a lot like creating any other type of assignment in MuseClass. You can initiate creating an AutoGrade assignment from either the Classes or My Library section.
Creating Assignments from the Classes Tab
You can create an assignment quickly from any class in the Assignments section. Here an option to "Create Assignment" is found.
You will see AutoGrade listed as one of the available assignment types to choose from once you hit the 'Create Assignment' button.
One MuseScore file per AutoGrade assignment.
AutoGrade assignments are tied to one MuseScore (.mscz) file. If you have multiple MuseScore files you want to use for different students, you can set up different AutoGrade assignments and specify which students or instruments you would like to assign the file to in the process.
Creating Assignments from My Library
You can also create an assignment from the 'My Library' section of your account by simply selecting the checkbox next to the title.
Once selected, a button saying 'Create Assignment' will appear and you can select the class to assign it to from here.
