Good question. The method praise is an instance method which means it will be part of an single instantiation of the Student class. The self signifies a reference to the current instance and the attributes, both class and instance attributes, it contains.

The parameter self Is automatically passed a reference to "this" instance to allow such references. 

# create instance
my_instance = Student()  
# call method 
my_instance.praise()

In this case self.name would be set to my_instance.name

Post back if you need more help. Good luck!!!
