Problem

• The view is expecting that when it tries to validate the student submission, a django.core.exceptions.ValidationError might occur.
• The view calls the submission service, which when it validates the submission, raises a custom class ValidationError, instead of the django.core.exceptions.ValidationError that the view was expecting
• this makes the view think that a completely different exception occurred, when in reality, we're just using the wrong class Fix
• in the submission service, use django.core.exceptions.ValidationErrorinstead of the custom class ValidationError
