This really looks like I'm converting to a string stringGPA(){ this.gpa.toString(); }

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

adding_methods.js 
class Student {
    constructor(gpa){
        this.gpa = gpa;
    }
  stringGPA(){
    this.gpa.toString();
  }
}

const student = new Student(3.9);

Try using return to return the string.

Perhaps you could try this:

class Student {
    constructor(gpa){
        this.gpa = gpa;
    }
  stringGPA(){
    return this.gpa.toString();
  }
}

const student = new Student(3.9);
