If you absolutely cannot pay, use the or ask your medical school’s disability/accessibility office if they can fund a subscription (visual learning aids are often covered as academic accommodations).

Introduction: The Artist Who Teaches Medicine In the vast ocean of medical education resources, few names resonate as powerfully with visual learners as Armando Hasudungan . A doctor, clinical educator, and artist, Armando has carved a unique niche. His whiteboard-style drawings—colorful, logical, and deeply detailed—have helped millions of medical, nursing, and pre-health students understand complex pathophysiology.

While the temptation to get something for free is universal, the cost (security risks, outdated information, ethical guilt) outweighs the benefit. Armando Hasudungan is one of the few educators who charges a genuinely affordable price—less than a Netflix subscription. His Patreon gives you instant access to hundreds of beautifully drawn, high-yield PDFs that can dramatically improve your grades.
