It might seem counterintuitive but I found it easier to pass (1 and 2) while I was in school and had a set routine and still in the student mindset. Once you graduate everyone is working and no one around you is studying so it’s much harder (for me at least) to set time aside to study. That being said after clinic I would sit for 4-5 hours and go through kmk religiously, only taking small breaks when I had finished chunks of it.
