Short U.S. citizenship test

I was linked to the following page, which contains questions from the U.S. citizenship test:

I scored 15/15, as the questions were easy to me and on that projection I could pass the test. How well can you perform?

Out of curiosity, I ought to see if the test or a variant of it can be found online; I am confident that my knowledge of the United States is strong enough for me to pass the test by a substantial margin.
