Tell us what’s happening:

Need help checking my code. What missing in the code? Although the output is same which is required on the console.

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) {
   let average = getAverage(totalScores);
   let grade = getGrade(studentScore);
  if (grade>=60){
    return "Class average: "+average+". Your grade: "+grade+". You passed the course.";
} else {
  return "Class average: "+average+". Your grade: "+grade+". You failed the course.";
}
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

hi there,

the problem is your if statement.
Try using hasPassingGrade function instead.

edit: just fyi: getGrade returns a letter score, so it cannot be compared reliably to a number like 60
