Alright, I need you make a new method named feedback. It should take an argument named grade. Methods take arguments just like functions do. You'll still need self in there, though.

If grade is above 50, return the result of the praise method. If it's 50 or below, return the reassurance method's result.

first_class.py 
class Student:
    name = "Mayank"

    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:
            praise(self):
        else:
            reassurance(self)

Hi Mayank,

You have a few small errors that need fixing.

Firstly, your feedback method needs to return something. As the Challenge states: "If grade is above 50, return the result of the praise method. If it's 50 or below, return the reassurance method's result." Right now you are calling the praise method or the reassurance method and those methods are returning values to your feedback method, but your feedback method doesn't do anything with those results.

Next, your position of self in your method calls is wrong. The purpose of self is tell your class where to find the method you are calling. So, if we had a method called 'sayHello' in our class and we wanted to call it from within another method called 'nextAction()' it would look like this:

def sayHello(self):
    pass

def nextAction(self):
    self.sayHello()

Remember also that self is automatically passed as an implicit argument when calling a function, so you don't add self as an argument yourself. Under the hood, if you called self.praise(self), Python would hand the praise method two arguments: self and self.

Finally, you have a typo at the end of the line where you call praise().

Cheers

Alex
