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){
     let isMajor = 'true'
     let _major = isMajor
  if (this.credits < 30 ){
  isMajor = 'false';
     _major = 'None';
  }else {

Here's a few hints:

The "let" operator creates a temporary variable that won't persist in the instance. To create a backing property, you would make an assignment using "this". For example: this._major = major;.

The extra variable "isMajor" isn't part of the instructions and is only being assigned and never used. You don't need it.

Finally, the value "30" identifies Freshmen from Sophomores. To identify Junior or Senior students, you'll need a different value.
