pass rates do tend 2 be high- but it does depend.
as said b4 recruitment usually pick the right people & the type of person they think is going 2 succeed.
2nd thing is the candidate- your the person choosing 2do this job & if you have the right frame of mind then you long 2 b told how somthing works/why its done like that/wot does that stand for?
when your passionate about the job your also passionate about learning- but its not a 9-5 training course- 2 pass the course & pass well you need 2 study after training too! i think training is one of the best parts- if its your first time then it may seem a little daunting but you soon get in2 the swing of it.
as long as u listen up/ study &have the will 2 learn then you have no worries & you will pass with "flying" colours!!
Good Luck.
