Phew. just done stage 1 testing today, and those folded cubes were hard!
There's a rumour that a few months ago selection tests for one particular occasion were mixed up for some admin mistake and someone who should have failed (a rather thick candidate) went through.
The trainee went on to the college and by the time the mistake was spotted, he had nearly finished his training.
He was then allowed to complete his training (successfully) and has now recently been posted to a certain unit very far up north
