I am a native to these shores, but I had a go at it out of curiosity and scored 18 out of 24 (72%). But I don't know what the 'pass' mark is, so I don't know if I would get in to the UK (theoretically).
80%. I think I got about 20/21 out of 24. The questions are mainly just factual ('what year did women get the vote? 'Is the following statement true or false?' 'What is the largest ethnic minority in Britain?')
I really don't see the point of the exam - it's just trivia. I don't think it serves any purpose (I can see what it's trying to do and it doesn't work). I think it would be much better to test language comprehension.
It froze, It wouldn't let me go beyond Betting & Gambling.
I also got 72%, I checked out my answers and found I had made a couple of silly mistakes, and was completely up the shoot regarding votes for women, highest numbers of ethnics and religion.
