About driving tests, about 8 years ago a colleague was doing her driving test and passed on second time. The second test was on a Friday with the head of the test centre. It was known by some locals, the city is a small one and a lot of people know each other.
Anyway, the centre had a max or min pass rate. Apparently if you failed after they had their max fail rate unless you were truly bad you got let off. So if you take your test at the end of the week and are borderline you are giving yourself the best chance to pass. Monday tests they'd fail you for anything.
Now I heard that from a few sources at different times but I have no idea if true. I hope not but things happen. Like the guy from Preston who took the test for about 200 other people and the thinking was that was not all of them. It be made the news.
