Bee Hero: Exam Review That Students Actually Want to Play
Exam review is easy to put off
Reviewing a subject usually means rereading notes and doing old tests. Students do it when they have free time, but rarely start when they need to. Bee Hero was built to turn the school's question sets into something learners want to open every day.
The app is a multi-topic quiz with "Featured Quizzes" and a "Quiz of the Day". Each question has a countdown timer and a progress bar, and the answer is marked right away.
Gems and rankings
Correct answers earn gems. Learners collect gems and move up the ranks, from Sapphire and Gold through Ruby and Emerald to Diamond. The home screen shows the user's rank and gem count on the first screen, so they always know where they stand.
This design draws on how students already play games: a number that keeps rising and a ranking that brings people back. That is my design reasoning, not a measured result.
Only school accounts can sign in
Sign-in accepts only addresses ending in `@fpt.edu.vn`. This keeps the ranking within the school community and keeps the question sets from being used by outsiders. The trade-off is that the app does not reach beyond that community.
Used at real events
Bee Hero was released for events organized by the school and for events run by a club I chaired. The app served more than 2,000 concurrent users. I planned the features, designed the app and wrote the code myself. The repository records 11 commits, from April 2022 to October 2026.
