You called getGrade here but what does getGrade need (as input) to work?

Also, you called hasPassingGrade, but what does that function need to work?

Make sure you give the functions what they need.

function studentMsg(totalScores, studentScore){
if (hasPassingGrade(getGrade(studentScore))){
return "Class average: " + getAverage(totalScores) + ". Your grade: " + getGrade(studentScore) + “You passed the course.”;
} else {
return "Class average: " + getAverage(totalScores) + ". Your grade: " + getGrade(studentScore) + “. You failed the course.”;
}
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

here is the code

The hasPassingGrade function takes a number as an argument (i.e. score) rather than a grade, so you shouldn’t be passing the getGrade function as an argument to it.

There is also a discrepancy in the string which you’re returning if the student has a passing score. Compare the final part of the string with the string which you pass if the student fails.
