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

const student = new Student(3.9, 10.9);

this should work , the this key word refering to a key in the new student object , and his dont have a key with the name tostring . second the to string is with capital s toString() and you forgat the second parameter .
