How it works · the science behind it

Rereading feels productive. Testing yourself actually works.

Four steps from first lesson to exam day. Each one is built on peer-reviewed memory research: you recall instead of reread, reviews are spaced just as memory fades, and practice mixes topics the way the exam does.

1

Pick your exam

Lessons follow the Ministry’s exam syllabus, one section at a time, and each opens with a map of where that section sits. Designer and General legal/process are complete; House lessons are being added in batches.

Learn, then test yourself

Each lesson opens with a quick guess, quotes the provisions word for word with a diagram and the reasons behind them, and ends with a three-question check, book closed, plus an open-book drill to find the article yourself. Start free: lesson 1 is open to all.

Review as it fades

Every question you check comes back: the next day if you missed it, in 3 to 7 days if you got it, then at ever-wider gaps. Each session mixes what’s due from all your lessons. For Designer legal/process, the study plan puts it all on a calendar.

Practise under exam conditions

Take a full mock exam: 70 questions from a bank of 400 or more, all topics mixed, with a running clock. After you submit, every answer shows its Code reference, and the lessons behind your misses come back in Review the next day. Live for Designer and General legal/process.
