What does this mean
Sorry, your code does not pass. Keep trying.

That means that there’s an error here in what you’re returning.

Hi there, welcome to fcc community.

I re-formatted your code a bit for better readability.
This is your studentMsg function:

function studentMsg(totalScores, studentScore) {
	const average = getAverage(totalScores);
	const grade = getGrade(average);
	if(grade == "F") {
		return "Class average: " + average + ". Your grade: " + grade + ". You failed the course.";
	}
	else{
		return "Class average:" + average+ " Your grade:"+ grade +" You passed the course.";
	}
}

First of all, let’s take a look at this line:

const grade = getGrade(average);

I supposed you want to get the grade of the student based on his score, right?
If so, is average the right argument for getGrade function?

Secondly, please carefully re-check for dots (.) and spaces in the output messages to matched the required format.

For the next time, for better assistance, you should create a pre-formatted help post to the forum by pressing the Help button. This button only appears after you tried to summit the code 3 times.

And to post your code to the forum, put your code between 2 line of ``` (3 back ticks) (the back tick key is usually under the Esc key on your keyboard), like this:

```
# your code here
```

Still the error is there

5

what does is even mean an average of 71.1 shouldnt get a grade of F since it passed

6

71.1 is class average.

The student score is 37. So his grade is : F

Please share your updated code.
