I took a dedicated period of 7 weeks during which I studied about 50-60 hours a week and took at least 1 day off a week. I didn't study for Step 1 prior to my dedicated period, but I had already done third year, and I did all the NBME clinical mastery series for each Shelf Exam, and I think this was really helpful to me.
As for resources, I used only Pathoma, First Aid, UWorld, both UWorld SIM forms, and the NBME Comprehensive Basic Science Self Assessments. I made Anki cards based on every UWorld and NBME question I answered incorrectly (and only the questions I answered incorrectly). I spent a lot of time reviewing all 6 current NBMEs to make sure I really understood every question (I took screenshots while I took the exam so I could see the questions I got correct as well).
I did not sit down and read FA until the week before my exam (I essentially read through it that week in the hopes of having some of it in my local memory), but rather cross-referenced sections relevant to questions I got wrong throughout my study period, so I only really read FA in the context of better understanding questions I got wrong. Overall, I really learned from questions rather than FA. For Pathoma I watched the videos and took notes in my book in the standard way.
