so far i have:

class Student:
    def __init__(self, first_name, last_name, numCredits, gpa):
        self.first_name = first_name
        self.last_name = last_name
        self.numCredits = numCredits
        self.gpa = gpa

        def getFirstname(self):
            return self.first_name

        def getLastname(self):
            return self.last_name

        def getNumCredits(self):
            return self.numCredits

        def getGpa(self):
            return self.gpa

        def setFirstname(self, first_name):
            self.first_name = first

        def setLastname(self, last_name):
            self.last_name = last

        def setNumcredits(self, numCredits):
            self.NumCredits = credit

        def setGpa(self, gpa):
            self.gpa = gpa

        def __str__(self):
            return (self.first_name, self.last_name, self.numCredits, self.gpa)

We don't do your homework for you we will only offer hints. So you need
to show us what you are trying and we will try to steer you to something

Normally yes, you'd make those variables the input parameters to the
__init__() method.

These would normally be defined inside __init__()

This is not good Python practice. It smells like Java...
In python it's customary to access attributes directly.
If you really want to use access methods then you
should create a 'property'

These are fairly standard.
