JavaScript Object-Oriented JavaScript Getters and Setters Creating Setter Methods

I don't get what I'm doing wrong.

so I wanted to test before asking a question so I ran this in the console, and it works so I was at a lost. modified the credits to 100 with student.credits = 100; which made the student a sophomore. with save math into major, as _major in the object.

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

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

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

    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';

var student = new Student(3.9, 60);

Those darned typos! The bane of tyros and gurus alike!

You wrote "junior" (with a lower-case "j") instead of "Junior" (with capital "J").
