The Student class has a gpa property on it, you can access by using

this.gpa

You then need to convert this value to a string as part of the method. you can do this by calling the .toString() method on it.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/toString

Your final code with the returned value should look like this:

class Student {
    constructor(gpa){
        this.gpa = gpa;
    }

  stringGPA() {
    return this.gpa.toString();
  }
}

const student = new Student(3.9);

Hope this helps, let me know if you need any further info.
