About

香港駕駛考試

Features
Read full description

This program is designed based on the "Road Users' Code" of the Hong Kong Transport Department and simulates the test questions of the Part A written test of the Hong Kong Driving Test. Candidates need to answer 20 three-choice multiple-choice questions within 20 minutes, and must answer 16 or more questions correctly to pass. This program has been carefully designed to make it easier for everyone to prepare for the exam. The program includes practice questions and simulated written tests. You can also browse test records, review previous mock written tests, and improve any shortcomings. In addition, there is also a collection function to browse previously collected questions. I hope these functions can help you prepare for the Hong Kong written driving test and help you take a pass!

Your child may not be “bad at maths”—they may be using an app built for another curriculum. Sobo Math follows Hong Kong EDB Key Stage 2 (Primary 4–6): 41 units and 231 stages on one clear map. This is an independent app, not an official EDB product. Why families choose us • Mapped to HK P4–P6: number, measures, shape, data, algebra • 4,900+ questions with interactive visuals and step-by-step help (not every item has a diagram) • Traditional Chinese, Simplified Chinese, and English text; Cantonese, Mandarin, and English read-aloud—script and voice can be set separately • Daily path, quests, and streaks • Sobo grows with practice XP (no pay-to-skip evolution) • Parent report: all weak-skill names free; one-tap practice on the first gap • Offline lessons, no third-party ads, no account Free includes every unit in order (daily energy limits how fast; later units unlock after earlier ones). Mock exam: 10 questions untimed. PRO: skip-ahead, unlimited energy, timed mocks (20–35 questions by year), unlimited adaptive review, full parent shortcuts and export. Practice papers here are school-style drills, not official TSA or school exam papers. Start free. Yearly plan may include a trial for eligible new subscribers (App Store terms). Subscriptions: Monthly HK$78 / Yearly HK$588 (~HK$49/mo). Auto-renews; cancel in Apple ID settings. Privacy: https://sisiyeung1126-max.github.io/math-games-ios/privacy.html
