[Question] Repeat Questions

Just wanted to second this concern. I have a high goal score and seem to have exhausted the question bank for advanced "assumptions" logical reasoning questions. I'm afraid this happened before I attained a high level of confidence in this type of question.

I've seen these questions before - in an Official LSAT practice book. Is there a way to know which tests were used in order to buy supplementary materials or just not repeat ones already seen?

Just want to second these concerns--I have practice tests that I want to take on paper (like the real thing) and want to avoid doing questions from those PTs. Also seeing a lot of repeats on the advanced level.
