I don't I saw any exam date posted. When thinking about the best and most efficient strategy, we should consider our timeframe and time commitment (ie. someone studying 5 hours a day for a month vs 2-3 hours a day for two months).
In general, I do believe the OG questions are perfect because like you mention they build on each another. I've tried several things and from what I've seen the only thing helping me on my practice exams have been the OG ones. Hope this helps a little. When are you taking your exam?
