Not getting correct return from a setter method..

Been at this one a while and not sure where I am going wrong here. Tried to reference the video before this challenge and still not able to see what I am missing. Any hints or explanations much appreciated.

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

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

    get major() {
        return this._major;
    }

    set major(major) {      
      if(student.level == "Senior" || student.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);

Hey Dehn,

It seems like youre trying to access the student object in the setter, but there is no student object in that scope. I believe you want to check the current student object that is calling the setter method. So youll need to use the "this" keyword. Replacing student.level with this.level will fix this.
