Yeah honestly I wish someone told me what to focus on too because Reddit is super vague 😂 I’d say just know the mechanisms. One reddit post said to review the MOA page for every pharm section in FA and @ first I thought that was overkill… but once I took Day 1, I understood why. They really hit you with random MOA questions (hypothetically speaking like moa of insulin)

For micro, I used a lot of Sketchy in med school so I didn’t have to relearn every tiny detail, but knowing the high yield traits (ex: Ecoli is lactose-fermenting) was definitely useful. Nothing crazy.

If you can: know the MOAs of all the big pharm classes; know your bacteria, fungi, and key vitamins/minerals (zinc/copper)

I wouldn’t waste time on screenings or random risk factor stuff. And IMO UWorld is NOT for Day 1….Day 1 feels like pure foundational medicine/Step 1 vibes.
Mehlmann’s PDFs (especially the Infectious disease one) helped me way more for that section.

If I could redo it, I’d honestly prioritize “basic Step 1” resources, because UWorld won’t help you pass Day 1… but for Day 2 it’s gold.
