Interactive Quiz Application: A Flask-based Assessment Platform

Project Report

Abstract

This project presents a dynamic web-based quiz application developed using Flask framework and SQLite database. The system provides an interactive platform for creating, taking, and managing quizzes while storing user responses and performance metrics. Built with modern web technologies including Flask, SQLite, and Jinja2 templating, the application offers a responsive user interface and robust data management system for educational assessment purposes.

1. Introduction

In the evolving landscape of online education, digital assessment tools have become increasingly important. This project addresses the need for a lightweight, efficient, and user-friendly quiz platform that can be easily deployed and managed.

1.1 Problem Statement

  • Need for accessible online assessment tools
  • Requirement for persistent storage of quiz results
  • Demand for real-time feedback and scoring
  • Necessity for comprehensive performance tracking
  • Challenge of maintaining user engagement

1.2 Project Objectives

  • Create an intuitive interface for quiz taking
  • Implement secure user authentication
  • Develop robust scoring system
  • Store and analyze quiz results
  • Generate performance reports
  • Enable quiz customization

2. Context and Background

The shift towards digital learning has accelerated the need for reliable assessment tools. Traditional quiz methods often lack immediate feedback and comprehensive result tracking capabilities. This project aims to bridge these gaps by providing a modern, web-based solution that enhances the quiz-taking experience while maintaining detailed records of user performance.

3. Methodology

The development process followed an iterative approach:

3.1 Planning Phase

  • Requirements analysis
  • System architecture design
  • Database schema planning
  • User interface wireframing

3.2 Development Cycle

  • Incremental feature implementation
  • Continuous testing
  • User feedback integration
  • Performance optimization

4. Technologies Used

4.1 Backend Stack

  • Flask: Web framework
  • SQLite: Database management
  • SQLAlchemy: ORM for database operations
  • Jinja2: Template engine
  • Python: Programming language

4.2 Frontend Technologies

  • HTML5: Structure
  • CSS3: Styling
  • JavaScript: Client-side functionality
  • Bootstrap: Responsive design

5. System Architecture

5.2 Database Schema 

CREATE TABLE users (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    username TEXT NOT NULL,
    email TEXT UNIQUE NOT NULL,
    password_hash TEXT NOT NULL
);

CREATE TABLE quizzes (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    title TEXT NOT NULL,
    description TEXT,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE questions (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    quiz_id INTEGER,
    question_text TEXT NOT NULL,
    correct_answer TEXT NOT NULL,
    FOREIGN KEY (quiz_id) REFERENCES quizzes(id)
);

CREATE TABLE results (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    user_id INTEGER,
    quiz_id INTEGER,
    score INTEGER,
    completion_time TIMESTAMP,
    FOREIGN KEY (user_id) REFERENCES users(id),
    FOREIGN KEY (quiz_id) REFERENCES quizzes(id)
);

6. Implementation Details

6.1 Core Functionality 

# Route for quiz submission
@app.route('/submit_quiz', methods=['POST'])
@login_required
def submit_quiz():
    quiz_id = request.form.get('quiz_id')
    answers = request.form.getlist('answers')

    # Calculate score
    score = calculate_score(quiz_id, answers)

    # Store result
    result = Result(
        user_id=current_user.id,
        quiz_id=quiz_id,
        score=score,
        completion_time=datetime.utcnow()
    )
    db.session.add(result)
    db.session.commit()

    return redirect(url_for('quiz_result', result_id=result.id))

6.2 Score Calculation 

def calculate_score(quiz_id, user_answers):
    questions = Question.query.filter_by(quiz_id=quiz_id).all()
    correct_count = 0

    for question, answer in zip(questions, user_answers):
        if question.correct_answer.lower() == answer.lower():
            correct_count += 1

    return (correct_count / len(questions)) * 100

7. UI Design

7.1 Key Features

  • Clean, minimalist interface
  • Progress indicators
  • Timer display
  • Immediate feedback
  • Responsive design
  • Score visualization
