Self-Check
No clock, no whole paper, no score to defend — this is the practice you do between attempts at the Exam Simulator. Pick one domain, take a quick 10, and answer each question cold: the moment you commit you find out whether you were right and read a short explanation of why. The options are reshuffled every session, so you’re recalling the answer rather than remembering that it was the third one in the list. Anything you miss is remembered on this device, so ↻ Past misses always has your weak spots queued up and ready to drill. Same shared question bank as the simulator — a very different exercise.
Reading the page about data gravity one more time feels like studying, but spotting the right answer in a list and producing it from memory are two different skills — the way you can point at your old house on a map without being able to describe the route there. So this page never shows you the answer first. You have to commit to one, and only then does it tell you. Getting it wrong is the useful part: a miss is an honest packing list. It names the exact box you still haven’t labelled.
Gizmo the Gremlin: You’ve read the 7 R’s page four times now. That’s basically knowing it. Skip the quiz, go straight to the timed exam.
Timmy the Turtle: That is the same argument as “the runbook looks fine, let’s skip the rehearsal cutover.” A plan nobody has tested isn’t a plan yet — it’s a hope.
Foxy: So test it. Ten questions, answered cold, no peeking. …Seven. I had replatform and refactor the wrong way round.
Professor Owl: And that is a wonderfully cheap place to find it out. Ninety seconds here, one mark on exam day, or a lost weekend halfway through a wave — same mistake, three very different prices.
The chip on each question names its domain, and the animal on it is that domain’s host from the Migration Academy — see Ellie on a question and you already know you’re carrying data. Clear a single domain at 70% or better and you earn that character’s 🏅 badge. Work one domain at a time instead of sampling everything: a run of misses all wearing the same animal is telling you precisely which lesson to reopen. For quick recognition drilling use the Flashcards, look terms up in the Glossary, run a real move against the Migration Checklist — and save the Exam Simulator for when you want the clock.
