Bummer: Whoops, the value returned from the stringGPA() method is not a string. -

My code

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

const student = new Student(3.9);

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

const student = new Student(3.9);

Since "toString" is a method, it needs to be attached to the value with the membership operator (period):

      this.gpa.toString();

Plus, you need to use the "return" keyword to give the value to the caller.
