Tell us what’s happening:

I dont quite understand why the function does not work properly , I even consulted another question related to this and tried to adjust it a bit to what the solution said and I dont get why it does not check out

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(getGrade) {
      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));

You have this existing function for checking the student grade.

And also the above link is not working. post correct link to the challenge step.

Ah indeed , I somehow ended up using getGrade instead of hasPassingGrade ,but , putting in hasPassingGrade(score) or just hasPassingGrade in the if condition does not get the test to work , also tried with studentScore as an argument.

function studentMsg(totalScores, studentScore) {

    if(hasPassingGrade(score)) {
      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));

studentScore is correct as an argument, but you have spacing issue. first give a space between if and condition () . second remove space before the word Class in both return statment. your code will pass.

thank you for the answer , also the space between if and the condition wasnt need but ofc I know its common practice to have one.Thanks again
