Unsure how to do this

Not quite sure how to structure this, looked online and the best method is .toString however I am getting errors.

adding_methods.js
class Student {
    constructor(gpa){
        this.gpa = gpa;
    }
  stringGPA(){
    return gpa.toString();
  }
}

const student = new Student(3.9);

Hi Martin! You forgot use the "this" keyword before the gpa.toString();

Hi, I have it the exact way you say, and I'm still getting "Whoops, the value returned from the stringGPA() method is not a string."
