FAQ

Common questions

Is the practice really free?
Yes. Every exam has 50 free practice questions with no signup, and a free account raises that to 75 and adds a full-length timed mock. After that, the full 1439-question bank and unlimited mocks unlock at pay what you want — and $0 always works. A tip is optional; it helps keep the banks current.
Is this affiliated with Anthropic?
No. Independent practice site. We don't issue the certs — Anthropic does.
Does the bank keep getting updated?
Yes — updates are free for everyone, forever. When Anthropic revises a blueprint, we refresh the affected questions at no cost.
What if I fail?
Use the post-exam analysis to find your weak spots and re-practice — everything stays free. If you tipped and would like it back, we review refund requests case-by-case (see /legal/refunds).
Can I share this with my team?
Just send people the link — it's free to start, and anyone can unlock the full bank at pay what you want, $0 included. If you need managed seats and a single invoice, see our team plans.
