Questions
Are these real exam questions?
No. Every question is original, written against the public exam guide. They are practice questions, not real exam questions.
Is this official?
Unofficial practice resource — not affiliated with or endorsed by Anthropic. “Claude” is a trademark of Anthropic, PBC.
What score should I aim for?
We use 72% as a rough stand-in for the 720/1000 scaled pass mark. The real exam is scaled, so treat it as a guide, not a promise.
Is it a subscription?
No. One payment, and it never renews.
Where is my progress saved?
In your browser on the device you use. Export it from the app and import it on another device to carry it over.
Can I get a refund?
Yes, within 7 days of purchase. Practice exams can be completed in full quickly, so the money-back window on exam-prep products is 7 days rather than the store’s usual 14.
