CBT is a Flutter application for Android and a unified academic assessment portal. Role-based access covers administrators, teachers, and students. Firebase Authentication signs people in, and Cloud Firestore syncs exams, sessions, and scores in real time. BLoC and Cubit keep business logic apart from the interface. go_router redirects each route from the authentication status and the user's role. shared_preferences stores local answer drafts, connectivity_plus watches the network, and the app logs switches during an exam.

- Export student score recaps as CSV
