I completed my ITIL foundation exam, like most exams, I just turned up at the test centre and sat the exam without any formal training.  I managed to pass and I now get to sport a green badge ;)

Since then, the resources that I've collated, I've placed in the documents section on the left.

I did consider sitting the service management exams, but they've made it so that you have to do about 6 weeks training before you can take the exams now!  Not sure I know anyone with the kind of time / training budet!
