Setter method returns undefined

This exercised asked to create a setter that shows the major of the student based on its level but, I always get undefined as the major value.

In any case, aren't setters supposed to be used when defining a new object? It seems counter intuitive to use a setter and not a getter in this case.

Hi Miguel. You are super close. If Level is Junior or Senior you want to set this._major = major NOT to this.level. this.level is Junior or Senior. you want to set this._major to the major being passed in.

Setters and getters aren't always needed, nor are they always used together. The choice to use one or both is based on the situation.

If you're having trouble with completing the challenge, we can give you help once we see your actual code.

I understand, here's a snapshot of my code: https://w.trhou.se/ykgn8qo9hi

student.level returns "Sophomore" but student.major is undefined

I tried using conditionals to set the major based on student.level but something isn't working and I can't figure out what.

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