I took this test officially earlier this year, scored 23/24 at the time, and redid it now with a fail of 18/24. Sshh, don't tell the Home Office! There are a HUGE number of other test questions available (they're randomly generated when you do the exam), with some of them even stupider than those listed here (eg, "Which statement is correct? A) The Queen is the heir to the throne B,) Prince Charles is the heir to the throne" and my personal favourite, "True or false: in the UK it is illegal to discriminate against women at work because of their sex"). If they're going to keep this test it really needs a massive rewrite...
