@MR172: Thanks for your reply, the point is I have not seen any comments box in the Polish CAA exam. You do the exam click that you are done and the PC immediately give you the result thats it. But I will do the Performance exam the last (got 3 sessions left after this session in case) so just in case it will not frustrate me for the other exams. And I will just remember the strange questions from question bank where they did not want factorized answer when asked about LDR and trust they got it right in question bank if I do not remember the question and answer (new question of this kind) then I do factorize if they ask LDR and hope for the best.
