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.

B. CURRENT STEP 3 STRUCTURE

Component	Official delivery model	Primary preparation target
Day 1 - FIP	232 MCQs; 12 blocks of 18-20 items; 30 min/block; about 7 h total.	Foundational science application, biostatistics/epidemiology, abstracts/drug ads, diagnosis and diagnostic studies, communication/ethics/safety.
Day 2 - ACM	180 MCQs; 9 blocks x 20; 30 min/block; plus CCS; about 9 h total.	Prognosis, health maintenance, therapeutics, longitudinal management and advanced clinical decisions.
CCS	13-14 interactive cases; each max 10 or 20 min real time.	Diagnosis, testing, therapy, timing, sequencing, location, monitoring, prevention/follow-up and disposition.

STEP 3 CONTENT SIGNALS WORTH PROTECTING

Signal	Official range / emphasis	Study implication
Patient Care - Diagnosis	~33-36% within day-specific physician-task specifications	History/exam, diagnostic studies, diagnosis, prognosis.
Patient Care - Management	~32-35% within day-specific physician-task specifications	Prevention, pharmacotherapy, interventions and mixed management.
Biostats / population health	11-13% MCQ system weighting	Interpret evidence, screening, risk and literature.
Communication / ethics / safety	7-9% MCQ system weighting	Professional next steps, safety and systems decisions.

4. FIP AND ACM EMPHASIZE DIFFERENT COGNITIVE WORK

DEEP EXPLANATION	WHY STUDENTS MISS IT	EASIEST CLUE
Day 1 leans toward foundations, evidence interpretation, diagnosis and diagnostic reasoning; Day 2 emphasizes prognosis, prevention, therapeutics and evolving management over time.	A single undifferentiated question-bank strategy can hide a weakness that appears only when task demands change.	Tag every miss by task: diagnose, test, treat, prevent, prognosticate, interpret evidence or manage systems/safety.
