Just remember guys that, whatever on line QB you are using, EASA is steadily replacing the questions, with the threat of legal action against any company or individual reproducing them in an on-line QB or other publication (although, how they intend to enforce this is beyond me!).
Apparently, feedback from UK examinations in November suggests that at least one subject was littered with new questions. One candidate claims that s/he only recognised 3 of the PoF questions from the on-line QBs and that all other questions were new!!! Whilst I wouldn't hold my breath on that dramatic a change being true (people often make mistakes) it could be that the new questions are being used already!
