This project is a full-stack web application built using React for the frontend and Express.js with MongoDB for the backend. The frontend uses various packages such as React-Axios, React-Router-Dom and React-Cookie to create a sign-up page and login page, a home page with Language selection and leaderboard features. The language selection feature enables the user to choose the language about which they want to give the test. Each language has various exercises that the user has to complete. User's progress is tracked during each exercise. Upon submitting they can see how much they scored. The Homepage also features a leaderboard feature where they can see top performing users across different languages. User's progress on each language is tracked in the user profile section and can also update their language preferences.

The backend uses packages such as bcrypt, cors, jsonwebtoken and mongoose to handle user authentication, password encryption, and database operations. It checks whether the user exists before storing the user's information in the database and uses JSON web tokens for secure communication between the client and server. Entire scoring logic is handled at the backend.

To use the application, users must first sign up with their email and password. Once signed in, they can choose language, attend exercises, see scores, check leaderboard, check their progress as well as upadte language preference. The application also provides a logout button to ensure the user's privacy and security.
