A mountain town at dusk in Certopolis: dozens of lit towers and houses standing on a headland, the sun going down behind a dark range under an orange sky.

Real certification prep

Revise for a real certification exam, and every answer raises your town

Real questions in the real exam's format — 1,837 of them, across two exams. Each domain of the syllabus is one building in your town, and the town stands on a shared coastline at an address that stays yours.

Practice for the exam you are actually sitting

Every question here is written to its exam's own published format — the same option counts, the same “Select TWO” where the real paper uses it, the same scenario-first phrasing — and the bank is weighted the way the exam weights its domains, so what you practise most is what you will be asked most. Nothing is paraphrased from someone else's course: a question is written from the primary documentation and cites it, and a citation that has gone stale is a bug we fix.

DVA-C02

AWS Certified Developer – Associate

901 questions across the exam's four domains, weighted the way AWS weights them: Development 32%, Security 26%, Deployment 24%, Troubleshooting 18%. Four buildings in your town, one per domain.

Anthropic platform

Claude Architect

936 questions across the exam's five domains, weighted the way the CCAR-F guide weights them: Agent Architecture 27%, Prompt Engineering 20%, Claude Code 20%, Tool Design 18%, Context Management 15%. Five buildings in your town, one per domain.

Want a different certification? These two have finished banks and others do not yet. The map needs no account, so there is nothing to sign up for in the meantime — go and look at the region and come back when your exam is here.

The question is the move

There is no lesson to sit through and no video to finish. You pick a domain and answer questions, and each one you get right raises the building for that domain — hut to cottage to keep. Get one wrong and it goes on your review list, where it stays until you have answered it correctly three times running.

A town from inside it at morning: houses and towers among trees, wooden signs naming The Chandlery and The Old Quarter, villagers on the paths and the sea beyond.

Your syllabus, standing up

Certopolis takes the exam's published domains and gives each one a building, at the weight the exam gives it. The tall one is the domain you are ready for. The short one is the one that will fail you, and you can see which it is from across the water.

A nearly finished woodland town at golden hour, its keep and tower standing above a ring of smaller houses, with a mountain range beyond.

Seventy-one towns already stand here

The region is a real coastline with Grandspire, the capital, at the head of it. The map is public and needs no account: go and look at any town on it, at its own permanent address, before you decide anything. Most of the towns are bots, and every one of them says so.

Nine kinds of ground

Where your town stands is your choice, and the ground dresses everything: the plants, the light, the animals, the townsfolk and what they wear. The buildings are the same everywhere, because they are your exam and not your scenery.

A green island town alone in open sea at golden hour, no other land in sight. — Island

A desert town under hard noon light, pale sand, a cliff wall standing behind it. — Desert

A tropical town among palms at golden hour, warm light across shallow green water. — Tropical

A large steppe city at golden hour, seven towers on open grassland gone gold. — Steppe

What is not in it

No video lectures.
No forty-hour course to get through before you may start.
No countdown timer, and no discount that ends in three days.
No upsell, no tiers, no bundle.
No pass guarantee. Nobody can honestly give you one.
No daily schedule telling you what is due.
No lives and no energy rationing how many questions you may answer.
No way to lose your town.

Nobody ever loses their town

A wrong answer can leave a building in disarray, and repairing it is a study session in the exact domain you are weakest in. Renown falls when you answer badly, but it stops one band below where everyone starts. Nothing you have built is ever taken away.
