Tell us what’s happening:

I do the code and it works as intended but cant pass the test.

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) {
  const classAverage = getAverage(totalScores).toFixed(1);
  const studentGrade = getGrade(studentScore);
  const hasPassed = hasPassingGrade(studentScore) ? "You passed the course.": "You failed the course.";
  return `Class average: ${classAverage} Your grade: ${studentGrade} ${hasPassed}`




}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));
console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));

You need a period after every sentence in the output string

could u explain how to add it as I add after ${} a . but other errors appear.
function studentMsg(totalScores, studentScore) {
const classAverage = getAverage(totalScores).toFixed(1);
const studentGrade = getGrade(studentScore);
const hasPassed = hasPassingGrade(studentScore) ? “You passed the course.”: “You failed the course.”;
return `Class average: ${classAverage}. Your grade: ${studentGrade}. ${hasPassed}
}
