A basic schema to creat quiz model

quizSchema.js

const { Schema, model } = require('mongoose');

// Answer Schema
const answerSchema = Schema({
    answer: {
        type: String,
        required: true
    },
    correct: {
        type: Boolean,
        required: true
    }
});

// Question schema, uses the answerSchema as type for options
const questionSchema = Schema({
    question: {
        type: String,
        required: true
    },
    options: [answerSchema]
});

// quizSchema takes in the questionSchema an Array of all questions
const quizSchema = Schema({
    category: {
        type: Schema.ObjectId,
        ref: 'Category'
    },
    quizName: {
        type: String,
        required: true
    },
    questions: [questionSchema]
});

const Quiz = model('Quiz', quizSchema);
module.exports = Quiz;
