Just to let you know, despite me doubting my sim, I managed to get through! For the record it was my 3rd attempt at the at the whole process and my 2nd attempt at the sim; so to all those that don't get through 1st or indeed 2nd time, don't be too disheartened.
Now just waiting for a start date!
Good luck everybody and thanks to everyone that contributed to the thread.
