Overview
The B2 extension of the A1 app — built for car-license learners, who face triple the question volume and significantly higher difficulty.
The challenge
B2 has a more complex structure than A1 (7 chapters, critical-fail questions), and regulations change yearly — content must be updatable without resubmitting the app.
The approach
Reused the content-as-data architecture from the A1 app: all questions, answers, and chapter metadata live in a remote JSON with offline-first caching. Added dedicated logic for critical-fail questions to faithfully simulate the B2 exam rules.
Outcome
5K+ downloads, 140+ reviews, 4.7★ on Google Play. Free since launch.
