My preview option is not working, anyway to get it to work?

My preview option is not working, anyway to get it to work? It says preview not available

first_class.py 
class Student:
    name = "Your Name"

    def praise(self):
        return "You inspire me, {}".format(self.name)

    def reassurance(self):
        return "Chin up, {}. You'll get it next time!".format(self.name)

    def feedback(self, grade):
        if grade > 50:
            return praise()
        elif grade <= 50:
            return reassurance()

I guess they didn't implement a preview for this challenge (odd the left the button there!). But if you go ahead and "Check Work", you'll get a "Bummer: Exception: name 'praise' is not defined".

That's a clue that you forgot to prefix your method calls with "self.".()
