I thought that I'd give the "Life in the UK" test - well, a random version available online - a go.
I passed, in 3m 43s, which is pleasing, as I have lived in the UK for 40+ years.
Mostly facts which are utterly irrelevant to life in the UK thought...
@neil I am now on question 5 and have yet to come across a question that would help prepare someone for life in the UK.
