I'm not seeing where my conditional statements are wrong? when i run it normally in VS code it runs fine

Per the title. I'm not understanding why my code isnt working anyhelp would be great!

creating_getters.js 
class Student {
    constructor(gpa, credits){
        this.gpa = gpa;
        this.credits = credits;
    }

   get level() {
        if ( this.credit > 90 ) {
        return 'Senior';
      } else if ( this.credit <= 90 && this.credit >= 61 ) {
        return 'Junior';
      } else if ( this.credit <= 60 && this.credit >= 31 ) {
        return 'Sophomore';
      } else {
        return 'Freshman'
      }
    }

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

const student = new Student(3.9);

Very odd that VS Code did not detect the error!

The logic is good, but the name of the attribute should be "credits" (plural) instead of "credit" (singular).

You seem to really know your stuff, so I was curious if there was a reason or any kind of gotcha that should discourage me from formulating my code as follows (this passed the challenge, fwiw):

get level() { if ( this.credit > 90 ) { return 'Senior'; } else if ( this.credit >= 61 ) { return 'Junior'; } else if ( this.credit >= 31 ) { return 'Sophomore'; } else { return 'Freshman'; } }

In other words, it seemed to me that you don't need to get explicit with the middle ranges since it's implied that credit ranges above have already been covered by the logic of the "else if". Hopefully that makes sense; I couldn't think of a better way to put it.

You're quite right, the high end of the range need not be checked since it would have been handled by the previous test.
