Version 3 is Bristol's database for the new NPA25 syllabus. This new syllabus has been introduced in certain european countries but not the UK, and the CAA originally said they were not going to use any V3 questions until the UK switched over to teaching NPA25.
Needless to say, although we're not teaching NPA25, we are getting V3 questions appearing in the exams. I took my first 8 exams last week and there were quite a few V3 questions in there - in Flight Planning there were loads. I hadn't really been through the V3 database before-hand (I went through afterwards to try and look up some of the questions) and although I don't have my results yet, I didn't notice any fiendishly hard questions that I had never seen before, so I think as long as you know your stuff and you're doing OK on the QB, you shouldn't worry too much about it.
