First of all, remember that name is part of the Student class, not its instance. Thus you should, by convention, rename self to be cls—short for class. Also, when accessing the name variable, you need to specify cls before it.

Second, note that the problem asked you to return the string, not to print it out.

def praise(cls):
    return "You're doing a great job, {}!".format(cls.name)

I hope this helps! :grin:

Happy coding! :zap: ~Alex
