Tell us what’s happening:

Please I don’t understand why my code isn’t passing.. I have tried even using string concatenation to get it but still not passing.. I need help

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";
}


// User Editable Region

function studentMsg(totalScores, studentScore) {
  if (hasPassingGrade ) {
    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));

If you look at the console, you should see that your function is outputting the following:

Class average:71.7Your grade:Fyou passed the course

Can you see the issue? Your return message should exactly match the requirements.

You could try adding this below your other console.log, for comparison:

// expected output
console.log("Class average: 71.7. Your grade: F. You failed the course.");

NOTE that your first console.log should have a studentScore of 37 (not 89).

Also, for your condition to work, it needs to feed a score as an argument into the function:

if (hasPassingGrade)

This is missing an argument.

Sorry for late response.. although I don’t really understand what you mean.. by what you showed me , I need my concatenation to be done properly right.. and what I found out with the console you showed me.. 71.1 showed the student got an F which is wrong.. so I would try a different stuff then come show you.. thanks

71.1 is the average, not the student score

5

Well I looked at it.. it seems I got it but the one problem I’m facing right now is the semicolon at the end of the sentence.. I can’t seem to get it right.. maybe I don’t know how to add the semicolon there

6 
  Sorry my bad.. what I wanted to say was a single string at the end of the sentence
7

Never mind I solved it.. thanks for your assistance..
