I just finished my ATPLs last month. The majority of the questions are new and you wouldn't have seen before, but i found studying really hard let me answer them anyway.
But, ATPL ONLINE is the worst question bank to help you study, mainly because they don't remove the questions that are wrong.
Use Aviation Exam or Bristol Ground School's question banks. You still wont see everything but the explanations are better and the exams are more representative.
A positive of EASA changing the question bank is they are also removing the ambiguous or really nasty questions. Every question i had over the entire exams was fair.
