      If an instructor has a data file, that has null scores for students,
      and the instructor imports that file, any existing scores will be cleared with
      those null scores.

      Example real-world scenario: when there are large classes, with multiple graders, who only grade a subset of the students.
      Each grader may only enter scores for their students, and have nulls for all the others.
