If I remember correctly the Italian QB was.... acquired by someone and sold to anyone with enough cash, or if you were lucky you would get one emailed free by someone?
It was not a site but was a genuine QB run by the Italian CAA, each country runs it's own bank of questions which are then pooled together, and then a mix is offered on exam day.
(I think this is how it works?)
This was a while back now and some of the questions are out dated but generally still useful.
