I've just got back from my third driving test, third time I've failed

I know it's not a huge crisis, but it is getting rather annoying. I thought it went well today, and one of the two things I got failed on, one of my friends did exactly the same and still passed!!!!!!!

True, it's all down to the individual examiner, and Sunderland test centre has a reputation for being the hardest to pass on; but is there something I'm missing? A secret handshake or wink, perhaps?
