Hi everyone.
I am doing the finalGrade() exercise. Similary, I have encountered the same error as @megacoder73951: Where the “helper” tells me that there is an error saying that 'If any of the grades passed in are less than 0 or greater than 100, the function should return ‘You have entered an invalid grade.’
Here are my codes:
// Write your function here:

const finalGrade = (num1, num2, num3) => {

const totalAmount = (num1 + num2 + num3) / 3;

if (totalAmount < 60) {

return ‘F’;

} else if (totalAmount >= 60 && totalAmount < 70) {

return ‘D’;

} else if (totalAmount >= 70 && totalAmount < 80) {

return ‘C’;

} else if (totalAmount >= 80 && totalAmount < 90) {

return ‘B’;

} else if (totalAmount >= 90 && totalAmount <= 100) {

return ‘A’;

} else {

return ‘You have entered an invalid grade.’;

}

}

console.log(finalGrade(90, 96, 92))
