проблем със задача 03. School Register от Objects and Classes - More Exercises

Здравейте, от известно време се мъча с тази задача но така и не мога да оправя кода, някой може ли да ми помогне ?

Благодаря :)

задача: https://judge.softuni.org/Contests/Practice/Index/1318#2

код:

function solve(input) {

let result = []

input.map(x => {

let[student, gradeInfo, scoreInfo] = x.split(", ")

let name = student.split(": ")

let grade = gradeInfo.split(": ")

let score = scoreInfo.split(": ")

if(grade[1] > 3.00)

result.push({name: name[1], grade: grade[1], score: score[1]})

})

function avg(){

return input.map(Number).reduce((a, v) => a + v, 0) / input.length

}

let sortedGrades = result.sort((a, b) => a.grade - b.grade)

sortedGrades.forEach(x => {

console.log(`${x.grade} Grade`);

console.log(`List of students: ${x.name}`);

console.log(`Average annual score from last year: ${avg(x.score)}`);

console.log();

})

}
