Hi there, still learning this myself so I apologise if I give you a wrong steer.

Quiz inherits from Step which has a foreign key course to the Course model.

So if you go into the Shell and import Quiz and Step then you can check that chain as follows:

>>> from courses.models import Quiz, Step
>>> q = Quiz.objects.get(id=1)
>>> q.title
'Review'
>>> q.description
'A quick review'
>>> q.course
<Course: Python Basics>
>>> q.course.title
'Python Basics'
>>>

As can be seen above q.course gives back the object Course

Hope that helps some!
