Tell us what’s happening:

Text of the outputs are identical yet it says that it’s not. I can’t see what’s wrong

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 score = getGrade(studentScore);
  const average = getAverage(totalScores);

  if (hasPassingGrade(studentScore)){
      console.log("Class average: " + average + ". Your grade: " + score + ". You passed the course.");
    }else if (!hasPassingGrade(studentScore)){
      console.log("Class average: " + average + ". Your grade: " + score + ". You failed the course.");
    } else {
      console.log("Wrong value");
    }
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

Your console says

Class average: 71.7. Your grade: F. You failed the course.
undefined

This is a huge clue. Where is that ‘undefined’ coming from? The ‘undefined’ is another symptom of why your code doesn’t pass.

Welcome to the forum @krikunenko.yulichka

Your code is outputting the text to the console.
Try returning it instead.

Happy coding
