Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

YEAR 1 CUMULATIVE REVIEW - END-OF-TERM

YEAR 1 | PAGE 46B - MECHANISM RECONSTRUCTION + CROSS-DOMAIN INTEGRATION

E. PASS 2 - RECONSTRUCT THE YEAR 1 SCIENCE SPINE

DomainBlank-page reconstruction targetTransfer question
Anatomy / neuroanatomyRegion map, neurovascular supply, compartments/spaces, tract/crossing/localizationIf this structure/tract is injured, what deficit or imaging finding follows?
Cell / geneticsOrganelle/trafficking, cell cycle, DNA repair, transcription/translation, inheritance logicHow does the molecular defect change cell function, inheritance and phenotype?
BiochemistryPurpose, location, inputs/outputs, rate-limiting step, regulation, fed/fasted stateWhat accumulates, what falls, and what organ/lab pattern follows a block?
PhysiologyNormal relationship -> perturbation -> compensation -> measurable outputPredict direction-of-change before naming disease.
Immunology / microbiologyHost defense arm + organism class/virulence + diagnostic signalWhich immune function or microbial clue explains the presentation?
Pharmacology / pathologyTarget/receptor -> physiologic effect -> toxicity; insult -> mechanism -> morphology -> consequencePredict the drug/pathology consequence instead of memorizing isolated associations.

F. FOUR INTEGRATION MAPS - USE THESE AS YEAR 2 SCAFFOLDS

Case spineConnect these Year 1 domainsOne discrimination prompt
AnemiaHematopoiesis -> iron/B12/folate biochemistry -> RBC morphology -> oxygen delivery -> pathologyIs the core failure production, destruction/loss, hemoglobin synthesis or ineffective maturation?
Sepsis / shockMicrobiology -> innate immunity -> cytokines -> vascular tone/permeability -> perfusion -> antimicrobial pharmacologyWhich mechanism explains hypotension and which intervention addresses the immediate physiologic threat?
DiabetesInsulin signaling -> carbohydrate/lipid metabolism -> endocrine physiology -> vascular pathology -> drug mechanismWhat changes between fed/fasted/DKA states, and what is the expected laboratory direction?
Neurologic lesionAnatomy -> tract/crossing -> physiology -> exam finding -> localization -> diagnostic testWhere is the lesion before you name the disorder?

G. TOP 10 MOST-MISSED CUMULATIVE-REVIEW CONCEPTS - #4 TO #6 — 4. Reconstruction should be causal, not encyclopedic Deep explanation

A useful cumulative map preserves the relationships that generate predictions: upstream/downstream, input/output, structure/function, trigger/response and compensation. Details that do not change a prediction can be re-added later if school objectives require them.

Why learners miss itStudents try to redraw every lecture slide and confuse detail density with understanding.

G. TOP 10 MOST-MISSED CUMULATIVE-REVIEW CONCEPTS - #4 TO #6 — 4. Reconstruction should be causal, not encyclopedic Deep explanation

Easiest clueAsk: What must I know to predict the next consequence?
5. Integration means one mechanism can be expressed in several disciplines Deep explanationA single case may contain anatomy, physiology, pathology, pharmacology and microbiology. Integration is the ability to move between those representations without treating them as separate facts.
Why learners miss it Easiest clueCourses are taught in modules, so learners store the same disease mechanism in separate folders. Use the chain cause -> mechanism -> finding -> test -> treatment across disciplines.
6. A compressed map is valuable only if it can regenerate detail Deep explanationOne-page maps should act as retrieval cues for a richer mental model. If the learner can recite the sheet but cannot solve a new vignette, the compression has become another memorized artifact.
Why learners miss it Easiest clueSummary sheets feel efficient and familiar, so they can hide shallow recall. After every map, solve one new case without looking at it.

G. TOP 10 MOST-MISSED CUMULATIVE-REVIEW CONCEPTS - #4 TO #6 — H. REPAIR LOOP FOR A RED MECHANISM Retrieve cold -> identify the break in the causal chain -> use one strong explanation -> redraw from memory -> solve a small targeted set -> retest with a new mixed item 24-72 hours later. Stop repair when transfer succeeds; do not finish a resource merely because you started it.
