Read full descriptionHide full description
Master HKDSE Physics in 10-minute focused drills — mechanics, electromagnetism, waves and more, all aligned to the HKEAA Curriculum & Assessment Guide. "DSE Physics Master" is built for Hong Kong DSE candidates. Physics rewards both clear concepts and precise calculation, yet many students lose marks on formula handling, unit conversion or experiment descriptions. We condense the whole syllabus into sharp 10-minute practice sessions that follow the HKEAA answering conventions. KEY FEATURES Full compulsory & elective coverage — Heat and Gases, Force and Motion, Wave Motion, Electricity and Magnetism, Radioactivity and Nuclear Energy, plus Astronomy, Atomic World, Energy & Use of Energy and Medical Physics. Step-by-step solutions that flag required units, significant figures and vector directions, with the keywords examiners look for in description and experiment questions. 100% ad-free, distraction-free study. Past-paper analysis (2013–2026): real per-topic average marks and question frequency so you spend revision time where it counts. Smart mistake tracking that logs every wrong question for targeted review. — Subscription — The Pro plan is an auto-renewable subscription at HK$68/month. It renews automatically within 24 hours before the end of each period unless auto-renew is turned off in your App Store account settings; your Apple ID account is charged on confirmation.
