The problem
Learner drivers in Vietnam struggle with fragmented theory resources, memorization of 600 questions, and practicing 120 hazard simulation video scenarios under timed exam conditions.
What I delivered
- Built a free community learning platform featuring the complete 600 official theory questions categorized by chapters with instant scoring and explanation tips.
- Implemented timed mock examination suites and interactive 120 hazard simulation scenarios to train hazard perception reaction times.
- Engineered offline practice capabilities allowing learners to review flagged or mistyped questions without active internet connection.
