From zero to useful,
one lunch break at a time.
Short, evidence-based crash courses with zero hype and zero signup. So far: AI at work, CDMP prep, the LSAT, and your ham radio licence. Start knowing nothing; leave able to do the thing.

Philosophy
Built on evidence, not engagement tricks.
Every design decision comes from the learning-science literature — retrieval practice, spaced review, scenario-based transfer — and the gimmicks the research says don't work were left out on purpose.
Modules of 6–10 minutes
One idea per module, honest time estimates, stop-and-resume anywhere. Your progress saves automatically.
Retrieval, not re-reading
Quick checks with instant plain-English feedback — the single best-evidenced way to make things stick.
Spaced review built in
Checkpoints reach back to earlier modules; optional calendar nudges bring you back before it fades.
Nothing gamified
No points, badges, streaks, or leaderboards. The evidence for them is weak; the annoyance is well documented.
The courses
Take your pick.
Every course runs on the same engine — the content changes, the learning mechanics don't.
The AI Crash Course
Understand AI well enough to use it at work — prompting that works, what's safe to paste, catching confident nonsense, and the ecosystem beyond the chat box. Tool-agnostic throughout.
Start the AI course →CDMP Prep
Data management certification prep, rebuilt on this engine — the DMBOK2's 14 knowledge areas, minus the sensation of reading the DMBOK2.
Start CDMP Prep →LSAT Prep
Logical reasoning and reading comp as short, spaced drills — the no-panic version of studying for it, built for the current test.
Start LSAT Prep →Ham Radio Technician
Your first amateur radio licence, taught as concepts rather than 400 flashcards — rules, electricity, bands, antennas, safety. No Morse code, no electronics background.
Start Ham Radio →What you'll walk away with
Concrete things you'll be able to do.
Not "literacy" in the abstract. Every course ends in specific moves — two from each, with the full list on each course's home page.
- AI — write a prompt that gets a usable first draft instead of generic mush.
- AI — know instantly what's safe to paste, and what should never leave your building.
- CDMP — tell data governance from data management on sight, in any question.
- CDMP — name the DMBOK knowledge area a question is really testing.
- LSAT — find the conclusion and the gap in an argument on the first read.
- LSAT — take a contrapositive without flipping it the wrong way.
- Ham — read a repeater listing — offset, tone, simplex — and program a radio from it.
- Ham — estimate a half-wave dipole for any band from the frequency alone.

Who's behind this
Built by someone who did it the hard way first.
Evan Cox is a multi-industry analytics expert and early AI adopter who's been putting these tools to work — at work and at home — for years, and made plenty of mistakes so you don't have to. These courses are the version of that experience he wishes someone had handed him: plain English, no hype, and the only thing they sell is competence.
Custom learning design
Want one of these for your team?
These courses run on a reusable, evidence-based engine — swap the content, keep the learning science. If your team needs training that people actually finish, let's talk.
Get in touch →FAQ
Questions you'd reasonably ask.
What does it cost?
Nothing. No account, no email, no "premium tier," no upsell waiting at the end.
How long do the courses take?
Modules run 6–10 minutes each, so a course is roughly 25 minutes on the casual lane and about an hour on the deep dive. Progress saves automatically, so stopping mid-module costs you nothing.
Which course should I start with?
Whichever one you'd use this week. They're independent — the AI course if you want to work with these tools, CDMP Prep if you're sitting the DAMA exam, LSAT Prep if you're taking the test, Ham Radio if you want a callsign. No order, no prerequisites.
Do I need an account?
No. Everything works without one. There's an optional Google sign-in if you want your progress to follow you across devices — it stores only your course progress.
What happens to my data?
Visits are counted anonymously — no cookies, nothing personal. Your progress lives in your browser unless you opt into sync.
Which AI tool does the AI course recommend?
None. It's deliberately tool-agnostic — the prompting, data-safety, and verification skills transfer across Claude, ChatGPT, Copilot, Gemini, and whatever ships next quarter.
Pick one. Zero hype.
Half an hour to something you can actually do — and you can stop whenever you like.
