Works great!
My wife used this app and passed the naturalization test and became a US citizenship.
Easy and work
I use this app for practice 30mins every day for a month and I passed the naturalization interview! This one really easy to use, when I answer the wrong answer then next round would show up again! Also the answers show all the correct you can practice and learn the same time.
