Your progress
Answer questions on the practice test and this page remembers which ones you know — free. Full access adds the review session that decides what to study and when, so what you keep missing comes back sooner.
Your progress is kept on this device, in this browser. There is no account and nothing is sent anywhere. Clearing your browser data clears it.
If you want the same schedule on your phone and your computer, you can turn on sync below. Sync copies which questions you have answered and when they are due. If you also turn on My Details sync, it copies the profile you filled in — your name, date of birth, address, country of birth, permanent-resident year and your state officials — so you do not have to type them again on another device. Both are off unless you turn them on, and you can turn them off and delete the copy we hold from this page.
Your N-400 interview answers never leave this device, under any setting.
