Tell us what’s happening:

The function studentMsg is correct by I don’t pass the test.
I calculate the average score of the class and also the grade of the student, with that and in a if statement I check to see if the student has passed the class then I return a string representing the message that tell if the student has passed the class.

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) {
  const grade = getGrade(studentScore);
  const average = getAverage(totalScores);
  
  if (hasPassingGrade(grade)) {
    return "Class average: " +  average + ". Your grade: " + grade + " grade-goes-here. You passed the course.";
  } else {
    return "Class average: " + average + ". Your grade: " + grade + ". You failed the course.";
  }

}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

Welcome to the forum @migule

Check the text for the two scenarios.

Also, console log what the if condition is checking.

Happy coding
