HOW CAN 22.point fail when code passes 20. and 21. points

Your code so far

function getAverage(scores) {
  let sum = 0;
  for (let i = 0; i < scores.length; i++) {
    sum += scores[i];
  }
  return Number((sum / scores.length).toFixed(1));
}

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(scores, studentScore) {
  const passed = hasPassingGrade(studentScore);
  if (passed) {
    return "Class average: "+getAverage(scores)+". Your grade: "+getGrade(studentScore)+". You passed the course.";
  } else {
    return "Class average: "+getAverage(scores)+". Your grade: "+getGrade(studentScore)+". You failed the course.";
  }
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));
console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));

Code already passes every topic up to 22 but fails at 22 how can it fail if it was able to pass 20 and 21 which LITERALLY CHECKS THE function studentMsg ?

For example, for console.log(studentMsg([92, 88, 12, 100, 67, 38, 97, 89], 37)), the expected message is “Class average: 72.875. Your grade: F. You failed the course.”, what does your function return?

It would be great if your example was included in the tests for this project, since all the others show a result with just one decimal point. A bit misleading.

return Number((sum / scores.length).toFixed(2)); you are a lifesaver :face_blowing_a_kiss:
