Ace the Test
Study for the US naturalization civics test, in English or Spanish
Ace the Test turns the civics test into short lessons you can finish in a few minutes, and tracks what you actually know rather than what you have merely seen. It is free, works offline, and needs no account.
Both versions of the test
USCIS replaced the 2008 civics test with a 2025 version, and which one applies to you depends on when you filed. Ace the Test has both, complete. The 2008 version is 100 questions across 21 lessons, where the interview asks 10 and you pass at 6. The 2025 version is 128 questions across 28 lessons, where the interview asks 20 and you pass at 12. Progress is kept separately for each, so switching between them never overwrites the other.
Completely bilingual
Every question, every answer, and the entire interface in English and Spanish. All 228 questions across both versions are translated, using USCIS's own wording wherever it exists. Change language whenever you like without losing any progress.
A path, not a pile of flashcards
Questions are grouped into five-question lessons, one USCIS category at a time. Finishing a lesson unlocks the next one. You always know where you are and what comes next, which is the part a shuffled deck of cards never tells you.
Four ways to practice
Multiple choice, typing the answer out, putting events in order, and matching pairs. The typed answers use a forgiving grader built around the real range of acceptable responses, so you are not failed for a missing "the" or for writing a number as a word. Each question carries a short note designed to make the answer stick.
Mastery, not just completion
A question counts as mastered when you get it right twice, not once. That is the difference between a lucky guess and knowing the answer, and only the second one helps you at the interview. A pop quiz draws from the whole set and scores at the same bar as the real interview.
Free, and private
The app is free and ads are what pay for it. There is no sign-up, no email address, and no password. Your progress lives on your phone and is never uploaded anywhere, because there is no server to upload it to.
Ace the Test is an independent study aid. It is not affiliated with, endorsed by, or funded by USCIS or the United States government. The questions come from USCIS's published civics test materials, which are works of the United States Government and are in the public domain.
