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.

IMMUNOLOGY

YEAR 1 | PAGE 12A - INNATE + ADAPTIVE IMMUNITY CONCEPT MASTERY

Build one connected immune-system model: BARRIER/PATTERN RECOGNITION -> INFLAMMATION/COMPLEMENT -> ANTIGEN PRESENTATION -> T/B-CELL ACTIVATION -> EFFECTOR RESPONSE -> MEMORY/TOLERANCE. The goal is to predict the immune response, not memorize cytokine lists.

  • Reconstruct innate recognition -> complement/inflammation -> antigen presentation -> T/B-cell activation without notes.
  • Explain MHC I vs MHC II, CD8 vs CD4 and how B cells receive help, class-switch and generate memory.
  • Predict consequences of losing complement, phagocyte killing, B cells, T cells or combined immunity from first principles.
  • Use cytokines/receptors as functional signals (who makes it, what it does, what disease/drug changes it) rather than isolated names. VIDEO-FIRST | SCHOOL-EXAM + BOARD-EXAM MASTERY
