I'm thinking that there should be:

Question Types:

• BasicQuestion - answer is a free text response (e.g. What is 1+1?: 2)
• MultiChoiceQuestion - multiple answer choices are presented, only one is correct
• MultiChoiceMultiAnswerQuestion - multiple answer choices are presented, any number (0 or many) can be correct, all correct responses must be selected

• AnswerChoice

        return score

        return self.score / self.assessment.max_score * 100

     answer_text: str(correct answer)
     answer_choices: M2M(AnswerChoice)


class AssessmentQuestionResponse:
    assessment_response: fk(AssessmentResponse, related_name="responses")
    question: fk(the question this response is for)
