CJayne is correct.
It does depend on how much you want the information and subsequently, how much you want that job!
I've had no hesitation in reading and often re-reading the posts, with great interest. In fact there were times when my reading got carried away late into the night!
I believe a decent degree of motivation is definitely required. Try to absorb the information on here. If you're really determined to get the job, frequenting this forum and other sources of information should help put you in the right frame of mind.
Best of luck. I have now booked my Stage 2, though it's not until the 18th August [earliest possible date!]
