Official 2025 CRAC question bank - 3,108 questions across Class A/B/C. Study, quiz, full mock exams, and a mistake book. Fully offline, auto-updates online.
HAM Exam CN is a preparation tool for the mainland China amateur radio operator technical ability verification exams (Class A, B, and C). All questions come from the official 2025 question bank published by the Chinese Radio Amateurs Club (CRAC).
All three question banks:
· Class A — 683 questions (entry level, VHF/UHF, up to 25W)
· Class B — 1,143 questions (intermediate, shortwave)
· Class C — 1,282 questions (full privileges, up to 1000W)
Pick your class on first launch, then switch anytime from the top bar. Study progress, mistake book, and mock scores are saved separately for each class.
Five study modes:
· Study — see the correct answers and review every point quickly
· Quiz — shuffled options, instant grading, wrong answers auto-saved
· Mock Exam — official rules, real question count, countdown timer, auto pass/fail
· Mistake Book — re-drill your wrong answers until you get them right
· Quick Reference — a cheat sheet of key exam points, with expand-all and print/PDF export
Thoughtful details:
· Fully offline — all banks are bundled, works with no connection
· Auto-updates — when the official bank changes, the app quietly downloads the update in the background
· Dark mode — follows your system appearance
· No ads, no third-party tracking, no personal data collected
