KIIP Study helps foreign residents in Korea prepare for the Ministry of Justice Social Integration Program (사회통합프로그램 / KIIP) exams. Passing them earns F-2-7 points, exempts you from the Korean requirement for F-5 permanent residency, and waives the language part of naturalization. PRACTICE WITH EXAM-STYLE QUESTIONS Questions written to match the format of the placement test, the mid-term (KLCT), and the comprehensive exam (KIPRAT for permanent residency, KINAT for naturalization), organized by level. Level 5 covers the permanent residency and naturalization tracks separately. WHY YOU GOT IT WRONG, IN YOUR LANGUAGE KIIP textbooks and Ministry of Justice materials are written in Korean only, so if your Korean isn't strong yet, you can see the right answer but not the reason. KIIP Study explains every question in 16 languages: why the correct answer is correct, and where your answer went wrong. SEE WHERE YOU'RE WEAK Your answers are grouped by topic and scored, so you can see exactly which subjects you keep missing, and drill those first. THE VOCABULARY THE EXAMS USE Most Korean apps (Duolingo, generic Anki decks, TOPIK textbooks) teach conversational or TOPIK-focused words that barely overlap with KIIP exam vocabulary. KIIP Study is built on the Ministry of Justice's official KIIP textbooks (한국어와 한국문화), from Level 1 to Level 5. Five question types (multiple choice, fill-in-the-blank, dictation, listen-and-type, and picture choice) rotate automatically, so you never see the same word the same way twice. WHO THIS IS FOR ◆ Level 1–2 beginners: you just registered for the placement test (사전평가) and don't know where to start. ◆ F-2-7 points seekers: Level 5 = 20 language points + 10 completion bonus (80/120 to qualify). Unlike TOPIK, KIIP certificates do not expire. ◆ F-5 PR & naturalization: Level 5 exempts you from the Korean requirement for most F-5 tracks, and waives the naturalization test and interview. ◆ F-6 marriage migrants: Level 2 meets the Korean requirement for F-6 renewal; Level 4 qualifies you for the F-5-2 PR track. ALSO INSIDE • AI-generated audio for words and example sentences • New first, then questions you got wrong or did long ago • Progress and stats: 7- or 30-day accuracy, questions answered, study streak • Optional study reminders: pick the days and time NO ADS, NO ACCOUNT No advertising, no ad-tracking SDK, no sign-up. Your study records stay on your iPhone. To improve the app, we collect usage statistics and crash diagnostics. This data does not identify you personally. No advertising identifiers, no study content. ABOUT KIIP The Korea Immigration and Integration Program is run by the Ministry of Justice, and anyone with an Alien Registration Card can apply. A 38,000-won placement test sets your starting level. Levels 1–4 are Korean language; Level 5 is Korean society and history. WHAT THIS IS NOT The questions here are practice items written to match the exam format, not actual past exam papers. This is not a grammar or speaking course; pair it with the official KIIP classes and workbook. You pass KIIP exams at 60 percent. Aim for 60, not 100. LANGUAGES The interface is fully translated into 17 languages. Definitions and explanations come in 16: English, Vietnamese, Simplified Chinese, Japanese, Tagalog, Thai, Indonesian, Khmer, Burmese, Uzbek, Mongolian, Kazakh, Russian, Nepali, Bengali, Sinhala. PRICING • Free: one vocabulary question, one exam question, and one hint every day. • KIIP Study Pro: no daily limit. Monthly, 3-month or yearly plans. Yearly saves about 40%. Subscriptions renew automatically at the same price unless cancelled at least 24 hours before the current period ends. Payment is charged to your Apple ID at confirmation of purchase. Manage or cancel any time in your App Store account settings. This app is not officially affiliated with the Korean Ministry of Justice.
