    let grade;
    // Write your code here
    if (score > 25 && score <= 30) 
        grade = "A";
    else if (score > 20 && score <= 25)
        grade = "B";
    else if (score > 15 && score <= 20)
        grade = "C";
    else if (score > 10 && score <= 15)
        grade = "D";
    else if (score > 5 && score <= 10)
        grade = "E";
    else
        grade = "F";
        
    return grade;
}
```

```javascript
function getLetter(s) {
    let letter;
    // Write your code here

        case "aeiou".includes(s[0]):
            letter = "A";
            break;
        case "bcdfg".includes(s[0]):
            letter = "B";
            break;
        case "hjklm".includes(s[0]):
            letter = "C";
            break;
        case "npqrstvwxyz".includes(s[0]):
            letter = "D";
            break;
    }
    return letter;
}
```

```javascript
/*
 * Complete the vowelsAndConsonants function.
 * Print your output using 'console.log()'.
 */
function vowelsAndConsonants(s) {
    const vowels = ["a","e","i","o","u"];
    const str = s.split("");
    const vowelsArr = [];
    const consonantsArr = [];
    for(let i = 0; i < str.length; i++)
        vowels.includes(str[i]) ? vowelsArr.push(str[i]) : consonantsArr.push(str[i]);
    for(let i = 0; i < vowelsArr.length; i++)
        console.log(vowelsArr[i]);
    for(let i = 0; i < consonantsArr.length; i++)
        console.log(consonantsArr[i]);
