Frequently asked questions

When does the beta open?

The CertWalk beta opens on November 1, 2026. Until then you can join the waitlist; we'll email you once when it starts.

What does CertWalk cost?

The beta is free. Whether CertWalk will be offered after the beta, and at what price, has not been decided. You will be told beforehand, and nothing renews automatically.

Is CertWalk an official Google product?

No. CertWalk is an independent learning service and is not affiliated with Google LLC. The official Google Cloud exam guide is the authoritative description of the exam.

Are these real exam questions?

No. All practice questions are written by us and aligned with the public exam guide. Sharing real exam questions violates the exam terms, so you won't find any here, and we ask you not to add any.

Will CertWalk make me pass?

Nobody can promise that. CertWalk helps you understand the content and practise the format. The simulator shows where you stand in each exam section.

Which languages are available?

Interface, knowledge pages, glossary and explanations are available in English, German and Spanish. Questions are in English, as in the exam, and also in Spanish. Audio: English with all 43 episodes, German and Spanish with the 14 main episodes each.

How do I sign in?

Without a password: enter your email address and you'll receive a sign-in link that is valid for 15 minutes. After that you stay signed in for up to 30 days.

What happens to my data?

We only store what the beta needs: name, email address, language and aggregated usage data. We don't store the content of your tutor conversations. You can delete your account in the app at any time. See the privacy policy for details.

How reliable is the AI tutor?

The tutor relies on CertWalk's knowledge pages but can still be wrong. If in doubt, double-check important statements, and please don't enter confidential or personal data.
