Every number and date on the civics test, on one page

Twenty-four questions on the 2025 test have a number or a year in the answer. Here they all are, grouped so they stick.

Numbers are where memory slips under pressure. Six or two? Nine or five? 1870 or 1920? On the 2025 civics test, 24 of the 128 questions have a number or a date somewhere in the accepted answer. Here they are in one place, grouped the way they connect, so you learn a pattern instead of a list.

How many senators does each state have?2

How to use this page

Read it once a day for a week, out loud, and the pairs start to hold each other up: 2 and 100 and 6 for the Senate, 435 and 2 for the House, 9 and 5 for the Court, 27 amendments, 1776 and 1870 and 1920 and 1929. Then take a practice test and see which ones still slip. The 2008 test shares most of these numbers, but it is a different question list, so if your N-400 was received before October 20, 2025, study the 2008 pool.
