Hi

function getAverage(scores) {

  let total = 0;
  for(const score of scores) {
    total += score
  }

  return total / scores.length;
}

function getGrade(score) {

  let grade = "";

  if (score === 100) {
    grade = "A+";
  } else if (score >= 90 && score <= 99) {
    grade = "A";
  } else if (score >= 80 && score <= 89) {
    grade = "B";
  } else if (score >= 70 && score <= 79) {
    grade = "C";
  } else if (score >= 60 && score <= 69) {
    grade = "D";
  } else {
    grade = "F";
  }

  return grade;
}

function hasPassingGrade(grade) {

  console.log(grade)
  if (grade === "F") {
    
    return false;

  } else {

    return true;
  }

}

function studentMsg(scores, studentScore) {

  const classAverage = getAverage(scores);
  const grade = getGrade(studentScore);

  if (hasPassingGrade(grade)) {
    return "Class average: " + classAverage + ". Your grade: " + grade + ". You passed the course."
  } else {
    return "Class average: " + classAverage + ". Your grade: " + grade + ". You failed the course."    
  }
  

}

console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

It’s not passing a single test:

19. Your hasPassingGrade function should return false if the grade is an "F".

Could it be a bug on your side or am I missing something here.

What do the instructions say about the parameters of hasPassingGrade?

  1. You should have a function named hasPassingGrade that takes a score as a parameter and returns either true or false depending on if the score corresponds to a passing grade.

  2. The hasPassingGrade function should use the getGrade function to get the letter grade, and use it to determine if the grade is passing. A passing grade is anything different from "F".

Are you doing what it says in instruction 3?

Yes it seems I might be missing the other point 4.

I updated the function hasPassingGrade below.
