JavaScript Object-Oriented JavaScript Getters and Setters Creating Setter Methods

I'm not sure what I did wrong :(

Inside the major() setter method, set the student's major to a backing property "_major". If the student's level is Junior or Senior, the value of the backing property should be equal to the parameter passed to the setter method. If the student is only a Freshman or Sophomore, set the "_major" backing property equal to 'None'.

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(student){
    this._major = major;

    if (this._major === 'Senior' || this._major === 'Junior'){
      return student;
    } else {
      return 'None';
    }
  }
}

var student = new Student(3.9, 60);

A setter should set, I think. Not sure if it makes sense to include a return value or not. The parameter name for the setter shouldn't be student as this doesn't describe the inbound value. The values for the comparison (sophomore, senior, junior) come from level. It seemed to pass with

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