Danify, Danish Exam Prep vs Big O Notation

Danify is a complete study companion for anyone preparing for the Danish citizenship exam (indfødsretsprøven) and active citizen exam (medborgerskabsprøven). Whether you're a newcomer to Denmark or have lived here for years, Danify makes exam preparation engaging, effective, and stress-free. Pass Indfødsretsprøven and Medborgerskabsprøven with the first AI-driven and fully multilingual prep app for Denmark's state exams. 5,451 practice questions, every one in English, Danish, and Spanish. 3,829 for Indfødsretsprøven across 32 master chapters and 249 sub-chapters. 1,622 for Medborgerskabsprøven across 16 master chapters and 110 sub-chapters. Every question, hint, and explanation is in your language for a better learning experience. WHY DANIFY Most prep apps for these exams are Danish-only. If Danish is not your strongest language yet, you spend your study time fighting the language instead of learning the content. Danify removes that wall: prepare in Danish, but if needed, switch to English or Spanish instantly, right on the spot! And when it counts, train under real test conditions in the Mock-Tests mode. MOCK EXAMS THAT MIRROR THE REAL ONE Every question in our bank is tagged by how it relates to past real exams: verified to have appeared, recurring across multiple sittings, high-frequency favorites, strongly aligned with exam patterns, current-events from the last six months, and broader civic knowledge/Danish values. Mock exams are sampled from these pools in the same proportions as the real exam. The Indfødsret Official round runs 45 questions in 45 minutes with a 36-question pass mark. The Medborger Official round runs 25 questions in 30 minutes with a 20-question pass mark. Both mirror the real SIRI format byte-for-byte, question-type-for-question-type. WEEKLY DANISH PULSE The Indfødsretsprøven includes current-affairs questions from the last few months. On our website, we publish a Danish Pulse digest every single week, so the questions you practice on Sunday cover the news from the week that just ended. An ever-expanding pool to guarantee you have the latest news in Denmark, right in your inbox and right in the app quizzes. AI EXPLANATIONS, ON DEMAND, IN YOUR LANGUAGE Stuck on a question? Ask. Our AI tutor explains the answer in English, Danish, or Spanish, with the historical or civic context that makes it stick. Already served 8,976 explanations and 8,622 hints to learners.
