To be fair to the CAA, this whole nonsense started with Europe, and the CTKIs of all the schools have helped to make the UK database the most logical. Aside from that, all involved should hang their collective heads in shame. As mentioned above, they had a golden opportunity, and screwed it. I don't believe it is going to get any better with the new EASA CEO either.
However, some questions have appeared in UK POF(H) exams that do not appear to be in the European database. I am told that 60% of the questions for POF(H) have now been disabled. If that is not an example of what we are talking about then I don't know what is.
