Tell us what’s happening:

function getAverage(scores) {
const total = scores.reduce((sum, score) => sum + score, 0);
return total / scores.length;
}

function getGrade(score) {
if (score === 100) return ‘A++’;
if (score >= 90) return ‘A’;
if (score >= 80) return ‘B’;
if (score >= 70) return ‘C’;
if (score >= 60) return ‘D’;
return ‘F’;
}

function studentMsg(totalScores, studentScore) {
const average = getAverage(totalScores);
const grade = getGrade(studentScore);
const passed = studentScore >= aver

}

console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));

Please Tell us what’s happening in your own words.

Learning to describe problems is hard, but it is an important part of learning how to code.

Also, the more you say, the more we can help!

Welcome to the forum @kagamejr

Try removing the .toFixed() method.

Happy coding
