USMLE Step 1 study plan

Build a single-page metabolic map linking glycolysis, gluconeogenesis, TCA cycle, and HMP shunt, marking every rate-limiting enzyme and the deficiency state that impairs it.

Write out the inheritance pattern, molecular defect, and one clinical clue for 15 high-yield enzyme and receptor disorders.

Explain aloud, from a blank page, how defects at replication, transcription, and translation each produce a distinct disease phenotype.

Sort 60 mixed practice questions by underlying mechanism (enzyme, receptor, transporter, structural protein) and record the mechanism behind every miss.

Close out general principles by writing a pharmacokinetic rule sheet (volume of distribution, first-pass effect, half-life, zero- vs first-order kinetics) and applying it to 10 drugs.

Draw the spinal cord cross-section at cervical, thoracic, and lumbar levels, label each tract, and predict the deficit from two described lesion cases.

Construct a 25-card deck pairing neurotransmitter, receptor subtype, second messenger, and one drug that acts at that receptor, and self-quiz to full recall.

Sketch the brainstem at midbrain, pons, and medulla from memory and match each cranial nerve nucleus to its lesion syndrome.

Build a table matching each major psychiatric disorder to first-line pharmacotherapy, its mechanism, and one characteristic adverse effect.

Trace the visual and auditory pathways and predict the specific field or hearing defect produced by lesions at three named points.

Explain from memory the pathophysiology of ischemic stroke, hemorrhagic stroke, and seizure propagation, and state the drug target used at each step.

Open the cardiovascular block by mapping the cardiac cycle onto simultaneous ECG waveforms, valve events, and pressure changes.

Draw the pressure-volume loop and the Frank-Starling curve, then show how preload, afterload, and contractility shift each one.

Assemble a murmur matrix covering timing, location, maneuver, and hemodynamic consequence for eight murmurs, and recite it without notes.

Classify antihypertensives, antianginals, and heart failure drugs by mechanism, and name one key contraindication for each class.

Map pulmonary mechanics: compliance, surfactant, and the pressure gradients driving ventilation and perfusion matching.

Work through 15 arterial blood gases using a stepwise acid-base algorithm and state the compensation for each.

Diagram the nephron segment by segment with its transporters, the hormone acting there, and the diuretic that blocks it.

Calculate filtered load, clearance, and fractional excretion for five clinical scenarios and interpret what each value implies about the lesion site.

Build a bilirubin and hepatic metabolism map that cleanly separates prehepatic, hepatic, and posthepatic jaundice by lab pattern.

Recite the major gastrointestinal peptides with their source, target, and effect, then predict the syndrome caused by a secreting tumor of each.

Map each hypothalamic-pituitary-end organ axis with its feedback loop and two classic deficiency or excess syndromes.

Compare insulin, the counter-regulatory hormones, and the major diabetes drug classes by mechanism, weight effect, and hypoglycemia risk.

Trace hematopoiesis lineage by lineage and label the growth factor or cytokine that drives each branch.

Build an anemia table organized by MCV that names the confirmatory lab value for every entry.

Draw the brachial plexus from roots to terminal branches and predict the motor and sensory deficit for four named lesions.

Classify primary skin lesions and describe ten high-yield dermatoses by distribution, morphology, and histologic finding.

Overlay the menstrual cycle hormone curves with endometrial changes and name the contraceptive mechanism that acts at each phase.

Trace male and female embryologic development and list the adult derivative of each duct, gonad, and external structure.

Re-run every error log from weeks 1 through 7 and re-attempt each missed item type until a second pass is fully correct.

Complete two 40-question mixed blocks under timed conditions and review every explanation, right or wrong.

Teach back your three weakest topics aloud in five minutes each with no notes, and note any point where you stall.
