I'm having a hard time with these getters and setters. Not sure how close I am with this, but this is all I have so far.

Can anyone help me with this setter question?

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

var student = new Student(3.9, 60);

You're pretty close Michael Glur-Zoucha!

It looks like in your setters conditionals you're using an assignment operator instead of an equality operator. Also, you will need to use this. to access the getter method. :thumbsup:

I'm so sorry, but I'm still not getting it. This is where I'm at now:

set major (major) { Student.level; if (this.level == 'Senior' || 'Junior') { this._major = major; } else if (this.level == 'Freshman' || 'Sophomore') { this._major = 'None'; } }

Is this what you mean?

Much closer Michael Glur-Zoucha :star:

This is what it needs to be:

set major(major) {
  if (this.level == 'Senior' || this.level == 'Junior') {
    this._major = major;
  } else if (this.level == 'Freshman' || this.level == 'Sophomore') {
    this._major = 'None';
  }
}
