  • The average score must be part of each item returns with key = averageScore.
  • A sample document in the collection is shown below:

    {
      "name": "Julia",
      "topics": [
        { "title": "Algo", "score": 10.5 },
        { "title": "C", "score": 10.2 },
        { "title": "Python", "score": 10.1 }
      ]
    }
