Bummer: level is not defined ?

I set the level () in get but can't use it in set. How can I use it in set?

class Student {
    constructor(gpa, credits){
        this.gpa = gpa;
        this.credits = credits;

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

    get level() {
        if (this.credits > 90 ) {
            return 'Senior';
        } else if (this.credits > 60) {
            return 'Junior';
        } else if (this.credits > 30) {
            return 'Sophomore';
        } else {
            return 'Freshman';

    set major (major) {
      if (level==='Senior' || level==='Junior') {
      this._major = major;
      } else {
      this._major = 'None';

var student = new Student(3.9, 60);

You're very close! When accessing components of the class itself, the identifier should be prefixed with "self.".

Hey, treehouse team, the answer did not help. Could you please just provide the clue?
