"self" on start_time but not on quiz_start?

In the "ask" method we created a log of the start time and the end time. This is then also done in the "take_quiz" method. However "self" is not used on the question_start but is used on the start_time variable. But self is included in both methods as an argument. How do I know when to use self and when not? I am aware that this is mentioned in earlier courses but it never sticks with me.

The first argument to any function that is a class method is self. It is also used to reference any variable that represents a property of a class object.

It's not used with question_start or question_end because those are simply local variables, and not class properties.
