Tell us what’s happening:

I’m not sure what I’m doing wrong. The function works and gives the correct result.

Your code so far

function getAverage(scores) {
  let sum = 0;

  for (const score of scores) {
    sum += score;
  }

  return sum / scores.length;
}

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

function hasPassingGrade(score) {
  return getGrade(score) !== "F";
}

function studentMsg(totalScores, studentScore) {
  let classAverage = getAverage(totalScores);
  let finalGrade = getGrade(studentScore);
  let passed = hasPassingGrade(finalGrade);
  if (passed = true) {
    return "Class average: " +  classAverage + ". Your grade: " + finalGrade +  ". You passed the course.";
  } else {
    return "Class average: " +  classAverage + ". Your grade: " + finalGrade +  ". You failed the course.";
  }
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));
console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));

Wrong argument in this function call.
let passed = hasPassingGrade(finalGrade);

I just tried it with the studentScore argument. Still not passing. I’m at a complete loss, since the function returns the correct values.

function studentMsg(totalScores, studentScore) {
let classAverage = getAverage(totalScores);
let finalGrade = getGrade(studentScore);
let passed = hasPassingGrade(studentScore);
if (passed = true) {
return "Class average: " + classAverage + ". Your grade: " + finalGrade + “. You passed the course.”;
} else {
return "Class average: " + classAverage + ". Your grade: " + finalGrade + “. You failed the course.”;
}
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));
console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));

Yes that correction should be right.

Also this: passed = true

You don’t need = true on this. Just the function call. I’ll test out the code above. Try the above as well.
