Tell us what’s happening:

My actual output vs the expected output are exactly the same but I’m still getting a “Your studentMsg function should return the correct message based on the student’s score and the class average.” error. Please help. Thank you.

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";
}

// User Editable Region

function studentMsg(totalScores, studentScore) {
    const classAverage = getAverage(totalScores);
    const studentGrade = getGrade(studentScore);
    const passed = hasPassingGrade(studentScore);

    if (passed) {
        return "Class average: " + classAverage.toFixed(1) + ". Your grade: " + studentGrade + ". You passed the course.";
    } else {
        return "Class average: " + classAverage.toFixed(1) + ". Your grade: " + studentGrade + ". You failed the course.";
    }
}
// actual output
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));
// expected output
console.log("Class average: 71.7. Your grade: F. You failed the course.")
// actual output
console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));
// expected output
console.log("Class average: 50.8. Your grade: A++. You passed the course.")

Welcome to the forum @swoosh_golfer

Happy coding
