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.

C. WHAT SCHOOL EXAMS COMMONLY REQUIRE

ResourceDescriptionLink
GFR / clearanceCreatinine/inulin/PAH concepts, clearance equations, RPF/RBF, filtration fraction and afferent/efferent perturbations.
Nephron transportSegment transporters, hormonal regulation, free-water clearance, concentrating/diluting urine and diuretic targets.
Volume / osmolalityHypo-/hypervolemia, serum/urine osmolality, urine sodium, ADH/RAAS logic and edema physiology.
ElectrolytesHyponatremia/hypernatremia, hypo-/hyperkalemia, calcium/phosphate/magnesium patterns and ECG/clinical consequences.
Acid-base / RTAAnion gap, Winter-style compensation logic, urine pH/urine anion gap and distal/proximal/type 4 RTA distinctions.
AKI / CKDPrerenal/intrinsic/postrenal localization; FENa/FEUrea concepts, sediment patterns, CKD complications and dialysis indications.
Urinalysis / glomeruliProtein, blood, casts, crystals, specific gravity and nephritic/nephrotic disease with microscopy/IF/EM clues.
Renal pharmDiuretics, ACE-I/ARB/RAAS effects, nephrotoxins, renal dosing and predictable electrolyte/acid-base adverse effects.

E. RENAL ERROR-LOG TAXONOMY — HEMODYNAMIC - wrong GFR/RBF/FF direction. TRANSPORT - wrong nephron segment/diuretic target. FLUID/ELECTROLYTE - wrong volume/osmolality or ion logic. ACID-BASE - primary process/compensation/RTA. URINE/PATH - sediment or glomerular pattern. THERAPY - renal dosing/drug consequence.

SCHOOL-EXAM GATE Proceed when you can predict serum and urine changes before answer choices, localize kidney injury from labs/urinalysis, solve clearance/electrolyte/acid-base problems, and explain how a renal drug or hemodynamic change produces the observed pattern.
