But: Bummer: gpa is not defined.

Question

Does anybody know what is wrong  with gpa?
Without me getting annoid by trying 1000 times over
```adding_methods.js
class Student {
    constructor(gpa){
        this.gpa = gpa;
    }
    stringGPA()
  {
    return gpa.valueOf(gpa);
  }
}
const student = new Student(3.9);
```

Hi. You're inside a class. So you need to refer to the gpa with this.gpa.
```javascript
class Student {
    constructor(gpa){
        this.gpa = gpa;
    }
    stringGPA()
  {
    // gpa here should be this.gpa. This way you refer to the instance of the class. 
    return gpa.valueOf(gpa);
  }
}
const student = new Student(3.9);
```
Also note that you probably want to return a string, valueOf doesn't really do that. Try figuring out what method to use for this or reply here and I'll help you. But for now you need to refer to gpa as this:
javascript
stringGPA(){
  // Note: this is not what you want, but just showing you how to refer to gpa.
  return this.gpa.valueOf(this.gpa)
}

If you got any more questions just write here :).
