Self-Check
The same question bank the Exam Simulator draws from, served here with the clock switched off. Pick a domain, take a quick ten, and answer cold: each question is graded the moment you click, and the explanation underneath says why the right option is right — and, more usefully, why the plausible-looking one isn't. Options are reshuffled on every pass so you're recalling the answer rather than its position, and your results are saved on this device, so Past misses is always a real list of the things you actually got wrong. This is the drill; the Exam Simulator is the dress rehearsal.
Reading a page again feels like studying, because the words look familiar the second time. But recognizing a sentence and being able to produce the answer with the page closed are two different skills — and only the second one is any use when something is broken at 3am. So close the page and try to answer first. Getting one wrong here is a good day: it costs nothing, and it hands you the exact topic to go re-read.
Foxy: I've read the deployment strategies page four times now. I'm good.
Remy: Then say it now, page closed: what does a blue/green cutover buy you that a rolling update doesn't?
Foxy: It... gives you... hang on.
Professor Owl: That pause is the entire point, Foxy. Recognizing a paragraph is not the same skill as producing the answer, and only one of the two survives contact with a real incident.
Timmy the Turtle: Same rule as production, then. Don't promote on "it looked familiar" — answer ten cold, read what you missed, run the misses again.
The chip on each question names its domain, and the animal on that chip is the same host who teaches it in the lesson — the Ship-It Guild roster in miniature. Filter to one domain and clear it at 70% or better to earn that character's 🏅 badge. When a miss is a vocabulary problem rather than a concept problem, the Glossary and the Flashcards are the faster fix; when you want the whole paper against a clock instead, go and sit the Exam Simulator.
