Tell us what’s happening:

I dont understand what I did wrong in the code here

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) {
  if (hasPassingGrade(studentScore)){
    return "Class Average: "+ getAverage(totalScores) + ". Your grade: " + getGrade(studentScore) ". You passed the course";
  }
  else {
    return "Class Average: "+ getAverage(totalScores) + ". Your grade: " + getGrade(studentScore) ". You failed the course";
  }
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

Hi there and welcome to our community!

You have the same syntax error in both of your return strings. You’re not concatenating correctly.

Once you’ve fixed that, there are a few other differences between your return string and the required string.

Here’s a handy debugging tip for you. Try console logging the expected output and checking it against what your function is returning:

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