The application follows the MVVM (Model–View–ViewModel) architecture.
- Views are responsible for the user interface.
- ViewModels contain presentation logic.
- Models represent application data.
- Services contain business logic and database operations.
Business logic is separated into dedicated services such as:
- AuthService
- MaterialService
- TestService
- UserService
- ValidationService
Entity Framework Core is used for data access with SQLite.
The database contains separate entities for users, tests, questions, answers, results and materials.
