just arrange the documents according to the checklist coz the UKVAk office will place your docs in their own brown envelope and plastic envelope ... lucky if you won't pass thru the fat lady coz she's kinda "not so friendly" or "suplada"
hehe I know who is that fat lady, when i lodge my visa saw that fat lady shouting to one applicant. she really has a loud voice and embarrased the guy.
