I found bristol a fantastic question bank! However don't fall into the trap that many people do by just learning the questions and answers rather than the actual theory behind the question. Will kick you right up the arse when you get to your first interview! In regard to downloading it onto your computer, you can go online and open up the question bank and then go offline and use it, however it is opened using internet explorer so when you finish it you will have to download it again. Italian feedback is very similar to Bristol but a little rough around the edges. You can get that on excel to use whenever you please!
