when i done it mate it was a four day course and an exam on the 5th day
you sit in a room with a tutor explaining everything to you and he gives you two booklets and you highlight what he tells you to.
alot of it is about law it is more for a bouncer than a security guard
hope this helps.
its a bit pricey though and you need to purchese the licence afterwords which is an extra 250 pounds
