On the 2025 test the officer asks one question at a time from the bank of 128, and stops the moment you reach 12 correct — you pass — or 9 wrong — you fail. So the test can be as short as 12 questions and as long as 20.
On the 2008 test it is 10 questions, stopping at 6 correct or 5 wrong. Under the 65/20 exemption it is 10 questions from the 20 marked ones, 6 to pass.
USCIS publishes a list of accepted answers for each question, and any one of them counts. "Who is the Father of Our Country?" — "Washington" is fine; "George Washington" is fine. You do not need the exact wording, and you do not need to give more than one answer unless the question asks for two or three.
This is where most practice apps let people down: they show one answer per question. This site shows every accepted answer, because the helper quizzing you at the kitchen table needs to know that "the Constitution" and "the U.S. Constitution" are both right.
About nine questions ask for a current office-holder — the President, Vice President, Speaker of the House, Chief Justice, your governor, senators, and representative. USCIS expects the person serving on the day of your interview. If an election or appointment happens between your study and your interview, the answer changes. The current answers, with the date we last verified them.
Your state's governor, your two U.S. senators, your U.S. representative, and your state capital depend on where you live. The officer expects your own. Look them up, write them down, and practise saying them — a surprising number of people know the President and not their own governor.
You are not denied on the spot. You get a second interview, usually within 60 to 90 days, and retake only the part you failed. Fail that too and the application is denied — but you can apply again.
The Official simulation mode on this site mirrors the stopping rule exactly: one question at a time, no going back, ends at 12 right or 9 wrong. Try it.
