Hey IH! 👋

Every year millions of people in Vietnam sit the driving-licence theory exam. In 2025 the law was overhauled — new licence classes, a 12-point system, higher fines — and most existing practice apps went out of date overnight (and were buried in ads).

So I built onthigplx.com: a free, ad-free way to practise, right from your phone, no signup needed. It has:

- The official 2025 set of 600 questions for every licence class (A1 to D1)

- Timed mock exams that mirror the real test, with an explanation for every answer

- The 60 "critical" fail-questions you must get right

- All 244 road-sign flashcards

It's bootstrapped and solo. Right now I'm focused on keeping the content 100% accurate to the new rules and growing through SEO, with a Pro tier planned to keep it sustainable.

Would love feedback from anyone who's built exam-prep or localized education tools — especially on retention and monetizing a free product without hurting the experience. Thanks!
