Tell us what’s happening:

I don’t get what I’m doing wrong. I don’t see any issues in my function logic yet it seems to be wrong. Help!

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) {
  // Obtenemos el promedio y la calificación
  let average = getAverage(totalScores);
  let letterGrade = getGrade(studentScore);

  // Construimos el mensaje base
  let message = `Class average: ${average.toFixed(1)}. Your grade: ${letterGrade}.`;

  // Añadimos el resultado final dependiendo de si aprobó o no
  if (hasPassingGrade(studentScore)) {
    return message + " You passed the course.";
  } else {
    return message + " You failed the course.";
  }
}

console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 45));

are you sure you are not doing something that is not asked for?

Well, I used some string formatting and some auxiliary methods yet I don’t see how it affects the result.

Somehow the string formatting was indeed affecting the result. Thank you for the hint.
