Tell us what’s happening:

I don’t understand right i think, can someone help me please?

function studentMsg(totalScores, studentScore) {
const average = getAverage(totalScores);
const grade = getGrade(studentScore);

if (grade !== “F”) {
return Class average: ${average.toFixed(1)}. Your grade: ${grade}. You passed the course.;
} else {
return Class average: ${average.toFixed(1)}. Your grade: ${grade}. You failed the course.;
}
}

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";
}
