the exam's six domains are one agent's workday. before it runs, its hands, what it remembers, the reckoning, colleagues, the rules of the house. full gh-600 course is up, 1h49m, free

the claude developer cert asks 53 questions but it only ever asks four things.
what runs. how it calls claude. what claude sees and says. whether it survives production.
built a full 3 hour exam prep course on that split. free

Where the numbers come from:
AI-102 retirement and the AI-103 successor path: Microsoft Learn
AI governance demand up ~150% year over year: LinkedIn 2026 Skills on the Rise
AIGP median pay ~$151,800 in the US: IAPP 2025 Salary and Jobs Report
AIGP exam fee $649 member / $799 non-member: IAPP
Search "best AI certification" and the lists still recommend AI-102.
That exam retired on June 30th.
An AI certification is a perishable good. Here is the 2026 breakdown of what they actually prove, how fast the badges decay, and four rules for picking one:
1. Match the vendor your job already runs on
2. Check the retirement date before you pay
3. One cert plus one shipped project beats three certs
4. Senior? Look at governance. AIGP holders sit around a $151k median and demand is up ~150% in a year

A 0-review course doesn't convert at any price. Mine has 0 reviews right now.
It's the paid version of my free Claude agent series: one real agent, 56 percent success rate to a stable 88, every number from a graded run.
First 100 seats are free. All I want back is an honest review. Good or bad.
Cheat sheet, question sampler and a four-week study plan: https://t.co/CCIxvYmU48
Two honest notes. Registration is partner-gated, so this gets you ready for whenever your door opens. And the questions are mine, written in the blueprint's style. They are not dumps.
Cert prep in AI has collapsed into question dumps. The Claude architect professional exam had four question banks on the market before anyone taught the material.
A bank hands you an answer. It never says why the other three options are wrong. That's the whole skill it scores.
So I built the course I wanted. 16 episodes, free, on the judgment the exam scores.
Every domain episode opens on a real production incident, teaches the mechanism, then works exam-style questions against it. Four failures taken apart end to end.
