Tell us what’s happening:

This stage seems so confusing for me and i do not understand why my code is not passing through. i am exhausted and 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) {
let classAverage = getAverage;
let studentGrade = getGrade;

if (getGrade){
  return "Class average:  totalScore + studentScore: grade-goes-here.  You passed the course."
} else {
  return "Class avearge:  totalScore + studentScore: grade-goes-here.  You failed the course."
}
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

Ok, let’s break this down.

Firstly, you need to pass arguments to the function parameters if you want to calculate the average score or the student’s grade.

let classAverage = getAverage;
let studentGrade = getGrade;

Next, your conditional statement should be checking whether or not the student has a passing grade or not. The getGrade function is not the correct function for this.

if (getGrade) {

Finally, your function should return the correct string value (with the relevant variables interpolated).
To interpolate variables, they need to be outside of the quote marks (e.g. "String" + variable + "string").
You also need to ensure that spacing, capitalisation, punctuation, spelling etc exactly match the required string.

"Class average:  totalScore + studentScore: grade-goes-here.  You passed the course."

Start by putting this at the bottom of your code so you can see what should be being returned by your console.log():

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

//i am getting right o/p still it’s not passing. don’t know why?
