Independent study material
AI engineering, studied on your own machine.
Study guides for how AI systems are built, evaluated and governed, with practice papers drawn to the published exam blueprints. Nothing runs in the browser, so the work is yours.
11 of 114 lessons are open to read without an account, and a free account opens the other 103. Creating one costs nothing.

Two things here work differently
There is no sandbox here, and that is the point
There is no hosted sandbox, no browser terminal and no pre-warmed container. The lessons describe the tools as you will meet them on your own machine: your shell, your installed version, your configuration files, your keys.
- No browser IDE and nothing to reset between attempts
- Version-sensitive claims are marked, not smoothed over
- What you set up survives the lesson
Why a sandbox teaches less
Most courses hand you a browser IDE with the dependencies already installed, the keys already set and the error you were about to hit already patched out. You finish the module feeling capable, open your own laptop, and none of it works.
Where a flag or a field name has moved between releases, the lesson says so and tells you what to check on your own build, because the honest answer depends on what you have installed rather than on what somebody pinned a sandbox to.
That costs you an evening at the start. It is the evening the learning is in.
The practice papers are built to the published blueprint
A certification programme publishes the shape of its exam: items per sitting, time limit, domain weights and the scale a result is reported on. Each paper here is drawn to those figures.
- Drawn fresh from a pool many times the length of one sitting
- Unseen questions first, so a second sitting is a different paper
- Scored by domain, so a weak paper tells you where to go back to
What the report gives you
Then it does the thing the real exam does not. Every option carries a written reason for being right or wrong, the ones you rejected included, and the report breaks the score down by domain so a bad paper tells you where to go back to rather than only that you failed.

The questions are original, written here from the published objectives. None of them is a real exam item, and a score here is a signal rather than a prediction.
What is in the library
Three courses, each an independent guide to a published exam blueprint.
How you study it
Four things, in the order you would actually use them on a Tuesday evening.
- 1
Read
Lessons set in a typeface built for long sessions, on warm paper that stays comfortable at night. Definitions expand inline.
- 2
Recall
Spaced repetition scheduled with SM-2. Cards you find hard come back sooner, cards you know drift further apart.
- 3
Test
A check after each lesson, a quiz per module, and timed papers under the clock the programme publishes.
- 4
Track
Completion, streaks and where you left off. Signed out it stays in your browser; an account carries it between devices.

Why you can weigh what it says
Exam facts come from the official exam guide.
Item counts, time limits, pass marks, scales and domain weights are read from the published guide rather than inferred.
Technical claims were checked against the vendor's documentation.
Product names, flags, fields and file locations were verified at the source rather than carried across from older courseware.
Every course states what it will not claim.
A ledger lesson in each orientation module lists what moves fast, and what to check against your own installed version.
It was a review by the people who wrote the material, and nothing beyond that. Nothing here is certified, endorsed or approved by any vendor or certification body.
Start with an orientation module
Every course opens with one, and it reads with no account at all. It sets out what the exam measures, how to prepare for it, and what the guide is and is not sure about.
11 of 114 lessons are open to read without an account, and a free account opens the other 103. There is no paid plan, no tier and nothing to buy.
