I have my RT test coming up soon and wondered if there were any reasons I'd be denied entry at all. I have no major health conditions. The only thing on my medical records are medicine for my knee a while back and creams for eczema. I experimented with cannabis but i will be clear for the medical. I have decent grades and a clean criminal record. Also, I'm going for warfare specialist (submariner) and i would prefer to be based in Faslane. Do i have a choice?
