Citizenship TestNumbers and dates to remember
Numbers are the answers people mix up most. Here they all are, taken from the official 2025 list, so you can learn them side by side.
There are 17 questions in the 2025 list whose answer is a number or a date. Almost all of them are in the 2008 list too, with the same answers. Learning them as one table, not scattered through 128 questions, makes the differences stand out: 100 senators but 2 for each state; a senator serves 6 years, a representative 2, a president 4.

Ways to keep them apart
- 2, 4, 6. Terms go up in twos: representative 2 years, president 4, senator 6.
- 100 and 435. The Senate is the small chamber: 2 senators × 50 states = 100. The House is the large one: 435, shared by population.
- 9 and 5. Nine seats on the Supreme Court; five is the smallest majority of nine.
- 13 and 50. On the flag, 13 stripes for the original colonies, 50 stars for the states today.
- 27. Amendments. The first ten are the Bill of Rights.
- 1776 then 1787. Independence first, the Constitution eleven years later.
- 1803. The Louisiana Purchase. 1920. Women vote. 1929. The Great Depression begins. 2001. September 11.
