Converting the property to a string?

I'm having trouble converting this to a string. I'm not sure what I am missing here. Can anyone tell me where I am making the error? Thanks in advance!

class Student {
        this.gpa = gpa;

  stringGPA() {



const student = new Student(3.9);

In your stringGPA() method, you want to return the gpa as a string. One way to do that would be:

return this.gpa.toString();
