The program runs questions but at the end does not print the summary.

Treehouse TeacherHi there, Tucker Fischer! It looks like you forgot the parentheses where you are calling the summary method. Right now it's returning a reference to the method instead of returning what is returned by running the method. Inside your take_quiz
method you have:
return self.summary # this references the method
But you meant:
return self.summary() # this calls/executes the method
Hope this helps!

method, check the variable spelling for self.end_time
.
print("It took you {} seconds total".format(
(self.edn_time - self.start_time).seconds
))
