Maximum call stack size exceeded

Im stuck on this code challenge. I dont really know what to do here. When I run it the error message: maximum call stack size exceeded appears. I would apreaciate it a lot if I got some help.

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){
        this._major = major;
        if(Student.level == "Senior" || Student.level == "Junior") {
            this.major = Student.level;
        } else {
            this.major = "none"; 
        }
    }
}

var student = new Student(3.9, 60);

Instead of using this.major in this.major = Student.level; and this.major = "none";, try using this._major. this.major without the _ calls the setter function.

You will also need to change Student.level to this.level and capitalize the n in "None". You could change this._major = Student.level; to this._major = major; or delete the line entirely, since it was previously set in the first line of the function.
