IvyMed's Step 1 formula sheet and memorize-before-test-day list. Part 1: 33 formula cards (biostats, cardio, renal and acid-base, respiratory, pharmacokinetics), ranked by how often each shows up across 4,261 official-style practice exam items, with how it's asked and the trap that costs people the point. Part 2: 226 pure-memorization facts on 36 cards (genetics, biochem, immunology, pharm, micro, anatomy, neuro, embryology, path), each with how often it's tested and a hook to remember it.
