||||
|
||||
A teacher has finished grading their students' tests and needs your help to calculate the average score for the class.
|
||||
|
||||
Complete the `getAverage` function which takes in an array of test scores and returns the average score.
|
||||
|
||||
The average is calculated by adding up all the scores and dividing by the total number of scores.
|
||||
|
||||
```js
|
||||
average = sum of all scores / total number of scores
|
||||
```
|
||||
|
||||
A couple of function calls have been provided for you so you can test out your code.
|
||||
|
||||
**Tips**
|
||||
|
||||
- You can use a loop to iterate over the `scores` array and add up all the scores.
|
||||
- You can use the `length` property to get the total number of scores.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `getAverage` function should return a number.
|
||||
|
||||
```js
|
||||
assert.strictEqual(typeof getAverage([92, 88, 12, 77, 57, 100, 67, 38, 97, 89]), 'number');
|
||||
```
|
||||
|
||||
`getAverage([92, 88, 12, 77, 57, 100, 67, 38, 97, 89])` should return `71.7`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(getAverage([92, 88, 12, 77, 57, 100, 67, 38, 97, 89]), 71.7);
|
||||
```
|
||||
|
||||
`getAverage([45, 87, 98, 100, 86, 94, 67, 88, 94, 95])` should return `85.4`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(getAverage([45, 87, 98, 100, 86, 94, 67, 88, 94, 95]), 85.4);
|
||||
```
|
||||
|
||||
`getAverage([38, 99, 87, 100, 100, 100, 100, 100, 100, 100])` should return `92.4`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(getAverage([38, 99, 87, 100, 100, 100, 100, 100, 100, 100]), 92.4);
|
||||
```
|
||||
|
||||
Your `getAverage` function should return the average score of the test scores.
|
||||
|
||||
```js
|
||||
assert.strictEqual(getAverage([52, 56, 60, 65, 70, 75, 80, 85, 90, 95]), 72.8);
|

Now the teacher needs your help converting the student score to a letter grade.
|
||||
|
||||
Complete the `getGrade` function that takes a number `score` as a parameter. Your function should return a string representing a letter grade based on the score.
|
||||
|
||||
Here are the scores and their corresponding letter grades:
|
||||
|
||||
| Score Range | Grade |
|
||||
| ----------- | ------- |
|
||||
| `100` | `"A++"` |
|
||||
| `90 - 99` | `"A"` |
|
||||
| `80 - 89` | `"B"` |
|
||||
| `70 - 79` | `"C"` |
|
||||
| `60 - 69` | `"D"` |
|
||||
| `0 - 59` | `"F"` |
|
||||
|
||||
|
||||
**Tips**
|
||||
|
||||
- Remember that you learned about conditional statements(`if`, `else if`, and `else`).
|
||||
- Remember that you learned about comparison operators (`>`, `<`, `>=`, `<=`, `===`).
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `getGrade` function should return `"A++"` if the score is `100`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(getGrade(100), "A++");
|
||||
```
|
||||
|
||||
Your `getGrade` function should return `"A"` if the score is `94`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(getGrade(94), "A");
|
||||
```
|
||||
|
||||
Your `getGrade` function should return `"B"` if the score is between `80` and `89`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(getGrade(80), "B");
|
||||
assert.strictEqual(getGrade(83), "B");
|
||||
assert.strictEqual(getGrade(88), "B");
|
||||
```
|
||||
|
||||
Your `getGrade` function should return `"C"` if the score is `78`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(getGrade(75), "C");
|
||||
```
|
||||
|
||||
Your `getGrade` function should return `"D"` if the score is between `60` and `69`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(getGrade(60), "D");
|
||||
assert.strictEqual(getGrade(63), "D");
|
||||
assert.strictEqual(getGrade(68), "D");
|
||||
```
|
||||
|
||||
Your `getGrade` function should return `"F"` if the score is `57`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(getGrade(57), "F");
|
||||
```
|
||||
|

Your `getGrade` function should return `"F"` if the score is between `0` and `59`.

The teacher is really happy with the program you have created so far. But now they want to have an easy way to check if a student has a passing grade. A passing grade is anything that is not an `"F"`.
|
||||
|
||||
Complete the function `hasPassingGrade` that takes a student score as a parameter. Your function should return `true` if the student has a passing grade and `false` if they do not.
|
||||
|
||||
**Tips**
|
||||
|
||||
- Use the `getGrade` function to get the student's grade. Then check if the grade is passing or not.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `hasPassingGrade` function should return a boolean value.
|
||||
|
||||
```js
|
||||
assert.strictEqual(typeof hasPassingGrade(100), "boolean");
|
||||
```
|
||||
|
||||
Your `hasPassingGrade` function should return `true` if the grade is an `"A"`.
|
||||
|
||||
```js
|
||||
assert.isTrue(hasPassingGrade(100));
|
||||
```
|
||||
|
||||
Your `hasPassingGrade` function should return `false` if the grade is an `"F"`.
|
||||
|
||||
```js
|
||||
assert.isFalse(hasPassingGrade(53));
|
||||
```
|
||||
|
||||
Your `hasPassingGrade` function should return `true` for all passing grades.
|
||||
|
||||
```js
|
||||
assert.isTrue(hasPassingGrade(87));
|
||||
assert.isTrue(hasPassingGrade(60));
|
||||
assert.isTrue(hasPassingGrade(73));
|
||||
assert.isTrue(hasPassingGrade(96));
|
||||

# --description--
|
||||
|
||||
Now that the teacher has all of the information they need, they want to be able to message the student with the results.
|
||||
|
||||
Complete the `studentMsg` function with `totalScores` and `studentScore` for parameters. The function should return a string representing a message to the student.
|
||||
|
||||
If the student passed the course, the string should follow this format:
|
||||
|
||||
```js
|
||||
Class average: average-goes-here. Your grade: grade-goes-here. You passed the course.
|
||||
```
|
||||
|
||||
If the student failed the course, the string should follow this format:
|
||||
|
||||
```js
|
||||
Class average: average-goes-here. Your grade: grade-goes-here. You failed the course.
|
||||
```
|
||||
|
||||
Replace `average-goes-here` with the average of the total scores.
|
||||
Replace `grade-goes-here` with the student's grade.
|
||||
|
||||
**Tips**
|
||||
|
||||
- Use the `getAverage` function to get the class average.
|
||||
- Use the `getGrade` function to get the student's grade.
|
||||
- Use string concatenation (`+`) to build the message.
|
||||
- Be careful with the punctuation and spaces in the message.
|
||||

||||
# --hints--
|
||||
|
||||
Your function call of `studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37)` should return the following message: `"Class average: 71.7. Your grade: F. You failed the course."`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37), "Class average: 71.7. Your grade: F. You failed the course.");
|
||||
```
|
||||
|
||||
Your function call of `studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100)` should return the following message: `"Class average: 50.8. Your grade: A++. You passed the course."`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100), "Class average: 50.8. Your grade: A++. You passed the course.");
|
||||
```
|
||||
|
||||
Your `studentMsg` function should return a the correct message based on the student's score and the class average.
|
||||
|
||||
```js
|
||||
assert.strictEqual(studentMsg([33, 44, 55, 66, 77, 88, 99, 100], 92), "Class average: 70.25. Your grade: A. You passed the course.");
|
||||
assert.strictEqual(studentMsg([33, 44, 55, 66, 77, 88, 99, 100], 57), "Class average: 70.25. Your grade: F. You failed the course.");
