Nonsense!
The QUIZ italian bank is still very useful. Rumour has it that this is the database of questions that started the whole jaa questions war.
Use it abuse it. You'll be surprised how many questions you'll find in the actual exams. All this CQB6/12/100 malarky is rubbish.
My advice... learn, i repeat learn your subjects, dont rely on questions. your cheating yourself. After you have learnt that lesson use the THE QUIZ and walk through the exams
