@Jamie.R - as a former Offsec student, you should understand that we can only give you so much info on that. I'd agree with the post, above - if someone is doing well in the lab, and understands not only the specific exercises and steps to pwn those targets, but the fundamentals of what they're seeing and doing, they SHOULD do well on the exam. If a person finds themself really struggling in the lab, then perhaps they should spend more time studying, before attempting the exam.
That's all I'll really give you, on that one, except to say, 'try harder' <evil grin> Put it this way, I'm currently studying for a second attempt on my OSCE exam. I thought I was ready, the first time, and, looking back, I was 'ALMOST' there. But I realized, after attempt #1, what I needed work on. So it's not always an exact science, of knowing the labs to ace the exam. Labs are preparatory, but not necessarily all-inclusive. Offsec is preparing you for the real world of pentesting. Hope you are enjoying the challenge!
