funtimewincies, your DH is right; that site doesn't appear to be 'genuine'. For a start it's not a gov.uk (all govt things are), it's a co.uk, so for all you know I could have set it up myself and plucked those questions out of the air (including the links to my online bookshop, of course). It actually says that these are not real test questions. There's no indication on that site of who owns it or set it up. There doesn't seem to be a link to it from the real government site about the test, which is here www.lifeintheuktest.gov.uk.
Calling it the 'Official Practice Citizenship Test' tries to make it seem 'genuine', but 'official' is a meaningless word in this context. I could call myself the Official Mumsnet Farthead, but it doesn't actually make it true. So in relation to this 'sample test', there's not much to get too outraged about! Therefore OP, YABU .
