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 "C";
  } else if (score >= 60) {

You have an extra space in your string. Compare it to the expected string.

". " + " You

I just removed all spaces there, its giving me the correct messages but the tests are not going through

You should not remove every single space. You need to put spaces in the exact same places where the sample string has them.

6

I did say “an” as in one.

For your original code, lets log it out and compare it to the expected message.

console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));
console.log("Class average: 71.7. Your grade: F. You failed the course.");

Logs

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

I have merged your two topics, please do not open new topics if you have already a topic open for a certain step

hasPassingGrade is a function, you are not calling it, so you can’t expect different values from it
