What’s on the USMLE Step 1 cheat sheet
- Pathology (45-55%) — cell injury, inflammation, and repair; apoptosis vs necrosis; neoplasia and the genetics of cancer — the densest discipline.
- Physiology (30-40%) — cardiovascular, respiratory, renal, acid-base, and endocrine mechanisms tied to the clinical picture.
- Pharmacology — pharmacokinetics, first- vs zero-order elimination, receptor mechanisms, and antidotes.
- Microbiology & Immunology — Gram-stain identification, high-yield toxins, MHC and antibody roles, and the four hypersensitivity types (ACID).
- Biochemistry & Biostatistics — metabolism and rate-limiting enzymes, inherited disease, plus sensitivity, specificity, and study design.
How to use it in your final week
- Front-load pathology and physiology — together they carry the bulk of the exam, so give the mechanism-heavy sections of the sheet the most passes.
- Weight your system review toward the high-frequency systems: reproductive and endocrine, respiratory and renal, and the nervous system.
- Read the sheet the morning of the exam for one last pass on memory hooks — hypersensitivity ACID, MHC rule of 8, first- vs zero-order kinetics, and the rate-limiting enzymes.
- Pair each review pass with a timed block (roughly 20 questions in 30 minutes) so the 8-hour, pass/fail day feels routine before you sit it.

It condenses the highest-yield basic science into a fast reference: pathology and physiology mechanisms, pharmacology kinetics and receptors, microbiology identification and toxins, immunology and hypersensitivity, biochemistry pathways, and biostatistics — grouped by the disciplines Step 1 weights most heavily.
Yes. Step 1 has been reported Pass or Fail only since January 26, 2022, with no three-digit numeric score, so the sheet is built to help you clear a confident pass rather than chase points. It also reflects the May 2026 delivery format of 14 thirty-minute blocks.
No — it's a review and last-week cram layer, not a substitute for full-length reps. Step 1 rewards reasoning from mechanism to answer across up to 280 clinical vignettes, so use the sheet to lock in facts and the practice test to build stamina and readiness.
