Computer Science from the Ground Up: How Computers Think and How Code Works — the free Preview

This page is the real first concept of Computer Science from the Ground Up: How Computers Think and How Code Works (Signature Course No. 332) — not a trailer and not a video. You work through Concept 1, “Computation Is Rule-Following,” in a Socratic conversation with an AI coach: she asks before she teaches, builds on your own answers, and holds you to a mastery bar before the concept counts as done.

What this course teaches. How computers think and how code works, from the ground up: bits and representation, algorithms traced by hand with every comparison counted, data structures chosen on evidence, the machine your code actually runs on, and the proven limits of computation itself. A computer understands nothing — and that is precisely why it can do so much.

How the Preview works. Meet Sutton, our Head Coach, then request your free Preview key — it arrives by email in a moment.

One concept, one five-minute conversation, coached exactly as enrolled learners meet it. When you’re ready for all 18 concepts, the full course is $195.
