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

const average=getAverage(717);
const grade=getGrade(37);

const studentMsg1="Class average: getAverage(); Your grade:getGrade(); You passed the course";
const studentMsg2="Class average: getAverage(); Your grade:getGrade(); You failed the course";

function studentMsg(totalScores, studentScore) {
  if (grade==="F"){
    return studentMsg2();
  } else {
    return studentMsg1();
  } 

console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

Hi @iskren500

You have a syntax message in the console.

SyntaxError: unknown: Unexpected token (49:23)
47 | console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37)); 48 | >
49 | // User Editable Region | ^

The two variables you created are not in the scope of the function.
Also, you need to pass the array to the function, not manually calculate the total.

Happy coding

I am confused, can you give me some tips please

what are you confused about?

what am I missing, it seems incorrect and won’t let me pass.
This is what I have:
const average=getAverage(scores);
const grade=getGrade(score);

const studentMsg1=“Class average: getAverage(); Your grade:getGrade(); You passed the course”;
const studentMsg2=“Class average: getAverage(); Your grade:getGrade(); You failed the course”;

function studentMsg(totalScores, studentScore) {
if (grade===“F”){
return studentMsg2();
} else {
return studentMsg1();
}

console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

you can’t call strings as functions and you can’t use variables that don’t exist. I suggest you only write inside the function
