Graded cells can be extracted individually or in groups to be evaluated by Mimir's testcase system.
Each graded cell also has a starter code attribute that can be used to provide your students a starting point.
Read-only cells can be used to provide examples or important code snippets that you don't want your students to override.
Notebooks in Mimir Classroom allows instructors to update their starter code and students to submit directly from the hosted environment.
