That would be true in an ideal world, James, with a question bank we can have confidence in, but we are dealing with multiple wrong answers and questions that do not make sense, so you cannot blame people for bashing the banks if that is what they have to deal with (Sweden detected that about 20% of the questions are just plain wrong). Put another way, you cannot get through the EASA exams on knowledge alone, with the current incarnation of the question bank (even with some of the new questions that are supposed to address that!). However, that does not help you with the tech interview!
Having said that, you can answer around 30% of the questions with common sense and PPL knowledge and with proper training materials most of the rest without resorting the rote learning.
