Tell us what’s happening:

Error keeps showing up even though i have the same result as the error, and i don’t know what to do.

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 averageScore = getAverage(totalScores);
  const studentGrade = getGrade(studentScore);

  const passOrFail = studentGrade === "F" ? "You have failed the course." : "You have passed the course.";

  return "Class average: " + averageScore + ". Your grade: " + studentGrade + ". " + passOrFail;
}
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));

Hi there and welcome to our community!

Your function works but your return message has a superfluous word in it.
Try adding this below your first console.log() for comparison:

// expected output
console.log("Class average: 71.7. Your grade: F. You failed the course.")

Thank you! The comparison helped a lot, i was too focused on other aspects and didn’t see the simple solution.
