Tell us what’s happening:

I am passing all the checks other than test 17. I am getting the correct result out of the function but for some reason unbeknownst to me, the function doesn’t pass.
Maybe a small typo or what can it be?!

Your code so far

// Get in the array and return the average of sum
function getAverage (array) {
  let result = 0;
  for(let num of array) {
    result += num;
  }
  return result / array.length;
}


// pass in the score and check what grade it is
function getGrade (int) {
  if(int === 100) {
    return "A+"
  } else if(int >= 90) {
    return "A"
  } else if (int >= 80) {
    return "B";
  } else if (int >= 70) {
    return "C";
  } else if(int >= 60) {
    return "D"
  } else {
    return "F"
  }
}

// Checks if getGrade function result is a passing grade
function hasPassingGrade (score) {
  return score !== "F" ? true : false;
}

// Show message to user if the grade is passable or not
function studentMsg (arrayScores, studentScore) {
  let averageScore = getAverage(arrayScores);
  let yourGrade = getGrade(studentScore);
  let passingGrade = hasPassingGrade(yourGrade);
  if(passingGrade) {
    return `Class average: ${averageScore}. Your grade: ${yourGrade}. You passed the course.`;
  } else {
    return `Class average: ${averageScore}. Your grade: ${yourGrade}. You failed the course.`;
  }

  
}
console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 60));

What is test 17? Which part of your code do you think meets the requirement?

Note - putting a space after a function name and before the ( ) for the argument list is pretty nonstandard for JS.

3
  1. Your hasPassingGrade function should return false if the grade is an "F" .

This one doesn’t pass the test, all the other are passing.

4

Please also answer my second question

5

The part where it returns true or false .

6

What part is that? Please quote or post just that function.

7

The result of hasPassingGrade(getGrade(59)) should return true or false, which it does, but the test doesn’t pass.

8

That is two functions. Which one is test 17 talking about?

9

As I said, function hasPassingGrade. hasPassingGrade function is taking as an argument the function getGrade which takes an integer as an argument.

10

Where does test 17 or the instructions say that? I don’t see it.

11

From the User Stories:

  1. You should have a function named hasPassingGrade that takes a score as a parameter and returns either true or false depending on if the score corresponds to a passing grade.
  2. The hasPassingGrade function should use the getGrade function to get the letter grade, and use it to determine if the grade is passing. A passing grade is anything different from "F".
12

I don’t think that’s what that part means.

It looks like the score is supposed to be the parameter as a number not a grade as a string. You aren’t passing a number to hasPassingGrade.

Ok, so I misinterpreted the:

The hasPassingGrade function should use the getGrade function to get the letter grade

as to pass the getGrade function as a parameter which is not correct.

I corrected my code and it has now passed with flying colors :upside_down_face:
Thank you for pointing that out. Cheers :melting_face:

so then what will be the code after you getting result ?

function hasPassingGrade(score) {
return score !== “F” ? true : false;
}

function studentMsg(totalScores, studentScore) {
if (hasPassingGrade(getGrade(studentScore))) {
return "Class average: " + getAverage(totalScores) + ". Your grade: " + getGrade(studentScore) + “. You passed the course.”;
} else {
