You are so close. The good order:

class Student {
    constructor(){

    }

    stringGPA() {

    }

    get level() {

    }

    set major (major) {
      let level = this.level;

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

var student = new Student(3.9, 60);
