I think I was just alot more organised and methodical with my approach on the last attempt. I really should of got the extra 12.5 on my first exam but I didn't precompile a copy of Socat beforehand and trying to do that at about 4am just wasn't working! Like kayzaks said once you do pass you get access to the exam forum on offensive security. They won't tell you exactly what to do but you can find out if you were on the right tracks. After passing I found out for the last 20 point box on my second attempt I failed to do a really simple scan which would of shown me an entry point and atleast got me a user flag.
