that actually get it.
Board-ready. Test-ready. No fluff.
Straight-from-the-source Q&A for the exams and boards that gatekeep your next rank, school, or paycheck — with the barracks humor to keep you sane while you grind.
The EATADIK line
Pick your field
Same no-BS method, every field with a high-stakes test. The Army edition is built and releasing now — the other five branches are working through the same pipeline behind it.
Army
The edition is complete — 31 titles. Three levels of board prep, the school pipelines, and a booklet for every core subject a board draws from, plus six print-only field references. 26,163 Q&A, every card cited to current Army doctrine.
The other five branches
Navy, Marines, Air Force, Coast Guard and Space Force are scanned and moving through review. We publish a branch when the whole branch is right, not one title at a time.
Survival
Field references for when the plan stops working. Survival Essentials is written and typeset and waiting on its cover art; urban, cold-weather, desert, jungle, water and disaster volumes follow it.
Aviation
FAA knowledge-test prep built from the official handbooks — written by a pilot, not a test-prep intern. Source material is scanned; decks are in review.
Maritime & licensing
USCG deck licenses and the civilian tickets that gatekeep a raise. Sourcing first — nothing ships until the doctrine behind it is verified public-release.
Trades & civilian certs
CDL endorsements, first-responder certification, real estate licensing and citizenship prep. On the roadmap, not yet in production — we'd rather say so.

Why it works
The method
No filler, no rephrased internet trivia. Just the questions that actually show up — drilled the way memory actually sticks.
Straight from the source
Every question pulled from official, publicly released manuals and doctrine — citation included, so you can verify us.
Cover & quiz
Question on one page, answer on the next. Cover, test yourself cold, flip, repeat.
Decoded acronym glossary
Not a list — a decode. The front section every soldier needs cold, in every single booklet.
Print & digital
Paperback in up to three trims, hardcover, and Kindle. Study anywhere.
Who wrote this
Not a test-prep intern.
EATADIK is written by Jeffery Alexander Smith — U.S. Army veteran, Cavalry Scout and Sniper, who stood the promotion boards these booklets prep you for. He went from answering board questions at parade rest to flying as a pilot — and built the study line he wishes someone had handed him.
"Every card cites the pub it came from. If you can't verify it, you shouldn't memorize it."
Every booklet: sourced like a staff study. Written like your squad leader.

Standing a board soon?
EATADIK — Army: Board Prep Lvl 1 (E-4 to E-5)
1,056 board-style questions and answers, every one pulled from current, publicly released Army doctrine and checked against what boards actually ask — plus the quick-reference front section and decoded acronym glossary that earn the book its shelf space on their own.

What we build next
Tell us what is missing
The Army edition is finished. What comes after it is decided by the people standing the boards, not by us guessing from a spreadsheet.
If you are studying for something and there is no decent book for it, say so. If a booklet we already built is missing a section you needed, say that too — that is the more useful message of the two.
