Why it works

🎛️

Interactive, not slides

Every lesson is something you do. Click, drag, and flip switches. The disease unfolds as you go, instead of sitting still on a slide.

💬

Everyday words first

Each topic opens with an everyday example. The clinical detail goes on top of that. It works the first time through and on review.

🧮

Real calculators

Type any values into the ABG Interpreter and the Punnett Square tool. Each one solves it step by step. Good for testing yourself.

📱

Works everywhere

It runs in any browser. Use a phone, a tablet, or a projector. Nothing to install, no account, no ads.
