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() !== "F"){
      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));

this needs an argument

Je ne comprend pas du tout le probleme

The problem is that you are calling a function that expects an argument without giving it an argument

this is getGrade

if you call getGrade() then score is undefined and the function will not give a sensible answer
