The official resources for civics test preparation give some answers that are not correct.
I have contacted the folks at usa.gov to point out one error in particular and I hope they will soon fix it.
Apparently 10% of people fail the civics test.... that shocked me.
See this link for the official pass rate:

Some of the questions/answers on the civics test are constant across time.
Other answers will change each time there is an election.
The official resource to get definitive answers to these election-based questions is here:

When I follow the links to get an answer to the question "Who is your State Governor" and enter Colorado as the State... I get a wrong answer!
The "official" answer on the "official" resource currently says
Governor John Hickenlooper
However, that answer is wrong... the correct answer using today's date (7/26/2019) is
Governor Jared Polis (he was elected in January 2019)
If just ONE person was deemed to have failed the Civics Test because of this, then that's one person too many.
I reported this error by mail and by phone to USA.gov so I hope to see it fixed soon.
I don't have the time or the energy to systematically proof-read all the answers for all the States and all members of Congress,Senate,Presidency,Vice President etc.
I wish that these types of questions were not actually on the civics test. After all, we can't vote for them so why should we actually know or care about their names (rhetorical question - no flames please). :-)
There are other wrong answers in the "official' resources
To get some insight into some of them.. read this article:
