Design approach for Multiple choice quiz app with Multiple right answers

Hi I'm trying to implement a django quiz app. But can't figure out the approach i should use when trying to create a question with multiple right answers. ie, users should be able to mark multiple choices as the right answers.

This is what I've come up with so far.

class Question(models.Model):
    question = models.CharField(...)
class Choice(models.Model):

question = models.ForeignKey(“Question”)

choice = modelsCharField(“Choice”, max_length=50)
class Answer(models.Model):

question = models.ForeignKey(“Question”)

answers = models.ForeignKey(“Choice”)

Please guide me how to implement it the right way.
