Tell us what’s happening:

dont seems to understand what is going on, and why the code is not passing

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) {
  function studentMsg(totalScores, studentScore) {
    // Calculate the average score
    const averageScore = getAverage(totalScores);

    // Get the student's grade
    const studentGrade = getGrade(studentScore);

    // Determine if the student has a passing grade
    const passingGrade = studentScore >= 60;

    // Create the message
    const message = `Class average: ${averageScore.toFixed(1)}. Your grade: ${studentGrade}. You ${passingGrade ? 'passed' : 'failed'} the course.`;

    return message;
}




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

Hi there!

Edit: Do not use toFixed method. Your code will pass without it.

Hi there,

This line is duplicated. Delete one:

Delete these 2 lines at the end:

Don’t use toFixed(1) method:

Because when the averageScore is 60 for example, then it will be displayed as 70.0, which didn’t match the output string as the test required.

Lastly, there’s a hasPassingGrade() function defined above you can use
