The August edition. Three big surfaces landed: a certification prep program, the course in five languages, and a rebuilt way to navigate all 503 lessons.
Certification prep, free and build-first
A new certifications section turns public exam blueprints into study paths you build through, not read through. The first program covers all four Claude credentials from the July 2026 exam guides (Associate, Developer, Architect Foundations, Architect Professional): 33 in-depth lessons, runnable labs, diagnostics, capstones, and 295 original assessment questions.
It is AI-native: Claude Code, Codex, Cursor, or any SKILL.md agent can teach a route, run the labs, quiz you, and resume your progress.

Independent community material: not affiliated with, endorsed by, or authorized by Anthropic. No live exam questions, no pass guarantees. Details in the announcement.
The course now speaks your language
Lessons are machine-translated into Simplified Chinese, Hindi, Spanish, Arabic, and Turkish, rolling out phase by phase. Pick a language from the site header or add ?lang=zh to any lesson URL; anything not yet translated falls back to English. The engine is NLLB-200 running free inside CI, with code, math, tables, and diagrams protected byte-for-byte. The README's landing copy is hand-translated into 12 languages. Details in the announcement.
Navigate 503 lessons like a map
- The roadmap is now an interactive dependency graph: see what unlocks what, top to bottom, instead of scrolling a flat list.
- The glossary grew to 243 terms across 12 learning areas.
- Every one of the 503 lessons now has an animated figure.
Learn in your terminal
Five learning skills install into any agent with one command: /start-learning builds a placement-based study plan, /learn teaches the next lesson interactively and tracks progress, /course-guide routes any topic or bug to the exact lesson, plus the placement quiz and per-phase checks.

Also in this edition
- Read lessons aloud with the browser speech engine, including diagram-aware narration.
- Quiz integrity fix: correct answers were biased toward the same option position across 2,026 questions; now uniformly distributed, with a CI guard.
- Statistics corrections in Phase 1: t-test p-values at large degrees of freedom and a chi-squared p-value that ran 7.5x too large.
- Homepage: cycling figure plates that explain the course, an evidence-backed learner wall, and a copy-ready install card.
