Preparing for the naturalization interview? This app has all 128 official civics questions for the 2025 version of the test - the one that applies to Form N-400 filed on or after October 20, 2025. The interview is spoken, not written. So this app is built to be practised out loud. A MOCK TEST THAT WORKS LIKE THE REAL ONE Twenty questions drawn at random from the 128. Twelve correct to pass. And the part other apps skip: the officer stops asking the moment the result is decided, at twelve right or nine wrong. Your practice test ends the same way. OFFICER MODE Questions read aloud, a pause for you to answer, then the accepted answers read back. Hands free, and it keeps playing with your screen off, so you can study on the bus or while you cook. Everything runs on your device - no internet needed. THE MISTAKES WALLET Every question you get wrong is saved automatically. A question only leaves your wallet after you answer it right twice in a row, and it comes straight back if you miss it again. KNOW WHEN YOU'RE READY Instead of an average score, this app runs thousands of simulated tests against your own answer history and tells you the thing you actually want to know: your chance of passing. THE ANSWERS THAT CHANGE Seven questions ask who currently holds an office - the President, the Speaker, your senators, your governor. Those answers change with elections and appointments, and an app that hard-codes them will eventually teach you the wrong one. So this one doesn't. You record what's true today, with a link straight to the official updates page, and it quizzes you on your own answers. ALSO INCLUDED - The 65/20 track: 10 questions, 6 to pass, for applicants 65 or older who have been permanent residents for 20+ years - A plain-English study guide across all eight official sections - Practice by topic, or shuffle all 128 - Your state's capital, senators and governor handled properly - Every answer that is accepted, not just one FREE TO TRY One full mock test, a study topic, a practice set and your ten most recent missed questions - free, no account, no sign-up. ABOUT THE CONTENT The questions and accepted answers are reproduced from USCIS publication M-1778 (09/25), a work of the U.S. Government. The multiple-choice options, explanations and study guide are original to this app. US Naturalization Test Prep is an independent study aid. It is not affiliated with, endorsed by, or sponsored by USCIS, the Department of Homeland Security, or any U.S. government agency. Some civics answers change because of elections and appointments - always confirm at uscis.gov/citizenship/testupdates before your interview.
