Tell us what’s happening:

I struggled to pass this lesson, but finally made it. What i noticed is that despite the score in the example given is 71.7 which grade should be “C” and therefore a passing score, the test is marking it as “F. You Failed the course”. This is not correct as the getGrade(score) function has all scores from 70-79 marked as “C” and is passing grade. This could be reason why many have referred to this as a “Bug”, please review. That is the only way the system will let you pass the test.

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));

But the 71.7 is the class average, it’s not the student score which determines the student grade. Student score for this case is 37, which is the F grade.
