You've proved what I've been saying to all our students to be right. None of the online apps or other practice questions can be anything like the 1000 brand new questions until way into next year, once they've somehow "stolen" enough questions. The only way to be ready before that is to know each individual subject inside out and upside down - so no question is a problem - before being recommended as ready by your club or school, which is how it was before apps were a thing............
