For task 2, it may have passed the challenge, but the instructions were not asking you to replicate what the parent class does. Instead, they were asking you to use "super" to call the parent function:

        super().add_item(item)

Then for task 3, there isn't anything name "list" defined. The list that needs sorting is the one stored in the class ("self.slots").
