Master key systems

Hello all , i'm trying to prepare for a locksmiths course in a couple of weeks and i am just trying to gather a little info prior to the
course so that i don't suffer too much information overload during the training .
Doesn't have to be concise , but will want enough facts to fit a small system of up to 10 doors with a couple of higher security keyed locks
or even a few tips to avoid disasters occurring ,
Thanks Guys !
