So I am taking part 1 on the 20th and here's how I am thinking about studying. Decks and old tests, 8th-14th detail on decks and tests. 14th to 19th. test simulation, only lookup missed or unsure answers after completion. Now I have older tests, but it has been brought to my attention that some questions or terms aren't valid. Any of you guys know how far back is safe to go? Thanks.
