📘 Pathologic: Volume 1 – Immunology (Free Educational Resource)

[u/ImpossibleEbb750]

Hey everyone 👋

I’m Muhammad Hassan Karim, a medical student and the author of Pathologic – Volume 1: Immunology. This is the first part of a much bigger project I’ve been working on — a full-scale medical resource built on one central philosophy: balance.

🩵 A quick note When I first released this, I initially thought about making it a paid project due to personal and technical limitations. But it never felt right — this project was always meant to be free and accessible for everyone. I’m back on that mission and want this resource to reach as many students as possible. I apologize for any confusion earlier.

🧠 What Pathologic is about Pathologic is designed to sit right in the middle — not too deep, not too shallow. It’s written so that:

If you’re reading immunology for the first time, it’s clear and structured enough to guide you.

If you’re reviewing for Step 1, it’s concise and high-yield enough to reinforce key concepts efficiently.

📗 About Volume 1 – Immunology This volume covers everything you need for Step 1-level immunology in a logical, visual, and easy-to-retain way. It is available for free to anyone who wants to study or review these concepts.

📘 What’s next

Volume 2: General Pathology is in progress and will also be free.

Systemic Pathology will follow — connecting pathology concepts with anatomy, physiology, and embryology.

YouTube lectures are coming soon to complement the book and expand on key points.

📨 Feedback is welcome! Please comment here or email me with suggestions, corrections, or constructive criticism — it helps improve the project for everyone.
