Tell us what’s happening:

I’m getting the correct return messages but failing the tests and cannot see why! Any help would be really appreciated.

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

Hi @willcampbellricketts ,

Welcome to the community.

Your code is almost correct. Just some minor tweaks.

We have to return a message from the function, not console.log() it.

One problem is, a dot is missing or extra in the code. So remove concatenating “.” with the grade and in the F condition above that. One way is to format the message in the return statement it like this :

return Class average: ${classAverage}. Your grade: ${getGrade(studentScore)}. You failed the course.

return Class average: ${classAverage}. Your grade: ${getGrade(studentScore)}. You passed the course.

Happy Coding!
