FAQ

Common questions

Is the practice really free?
Yes — all of it. You can start with 365 questions and a full-length mock with no signup, and everything beyond that is unlocked by a pay-what-you-want tip where $0 always works — so the full 1439-question bank and unlimited mocks are free either way. 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?
It's free, so just send people the link — there's nothing to unlock. If you need managed seats and a single invoice, see our team plans.
