Yo,
These were my steps:
First 2.5 weeks: Forced myself to go through all of the fmCases in detail (about 45 min per case), taking some brief notes on big topics
Week 2.5-3.5: Read through all of the PDF summaries once and made handwritten study sheets with key concepts
Last day: Read through my study sheets once
I was sick right before the shelf and didn't have a lot of stamina/tolerance for studying for that one- I still did fine. I think the most helpful thing was working through the cases- it's just hard to actually force yourself to engage with them and not click through willy nilly.
Hope that helps!
