JavaScript Object-Oriented JavaScript Getters and Setters Creating Setter Methods

I'm probably being really stupid here but why is this not accepting my setter method?

I am getting an error telling me my setter method is returning the wrong thing. I've tried the code in a different editor and it works. Have I maybe misunderstood the question? Thanks.

creating_setters.js 
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(student.level === 'Junior' || student.level === 'Senior') {
            return this._major = major;
        } else {
            return this._major = 'None';
        }
      }
}

var student = new Student(3.9, 60);

Try changing student.level to this.level so that if there are multiple students, each will check their own level and not the level in the student variable.

Values returned from a setter get ignored, so you can remove the return keyword.
