What you are buying, and from whom.
Last updated: 24 October 2026
Who sells this
The Study Kits are published by DestrezaAI, contactable at contact@destrezaai.com.
Payment is taken by Lemon Squeezy, which acts as the merchant of record. For your purchase they are the seller: they charge you, they handle VAT in your country, and they appear on your bank statement and on your invoice. Their terms apply to the transaction itself.
The products
This site publishes several Certification Study Kits, one per certification. Each is bought separately and each has its own license key. The current list is on the home page.
| Study Kit | Where it lives |
|---|---|
| AWS Certified AI Practitioner (AIF-C01) | destrezaai.com/aws-ai-practitioner/ |
| Azure AI-103: AI Apps and Agents Developer | destrezaai.com/azure-ai-103/ |
| AWS Certified Cloud Practitioner (CLF-C02) | destrezaai.com/aws-cloud-practitioner/ |
| Microsoft Azure Fundamentals (AZ-900) | destrezaai.com/azure-fundamentals-az900/ |
| Microsoft Azure AI Fundamentals (AI-901) | destrezaai.com/azure-ai-fundamentals-ai901/ |
| Google Cloud Professional Machine Learning Engineer | destrezaai.com/gcp-ml-engineer/ |
| GCP Generative AI Leader | destrezaai.com/gcp-generative-ai-leader/ |
| Google Cloud Professional Agentic Architect | destrezaai.com/gcp-agentic-architect/ |
These terms apply to all of them, and every one is sold on the same basis:
- What it is
- One Study Kit per certification, with three learning tools: Concept Maps (an interactive map of every exam section), Flashcards (spaced repetition on the key terms) and a Practice exam (original multiple-choice questions with a written explanation for every option). The exact numbers vary by exam; see each product's own page
- Price
- €10, VAT included
- Payment
- One payment. No subscription, nothing recurring
- Delivery
- Immediate, by email, as a license key
- Access
- In your web browser. Nothing to install
- License period
- 1 year from the date of purchase
Free content from each Study Kit is available on this site with no purchase and no sign-up: ten practice questions, the Concept Map and the Flashcards of the first exam section. Paying unlocks the rest of all three tools.
A license key unlocks the Study Kit it was bought for. It does not carry across to another Study Kit.
How delivery works
When your payment goes through, a license key is emailed to you automatically. Paste it into the site and the full Study Kit unlocks. Your key works on up to five devices; each is remembered separately in its own browser, so you paste it once per device and not again after that. If you need it reset on a sixth, write to us.
If the email does not arrive, check your spam folder first, then write to us at the address above and we will resend it.
Your license
Your key gives you access to the full Study Kit for one year from the date of purchase. Use it for your own study, on your own devices, for as long as that year runs.
You may not resell it, republish it, or share your license key publicly. A key that appears in public can be revoked.
The questions, concept maps, flashcards and explanations are original work and remain the property of the publisher.
Right of withdrawal
EU consumers normally have 14 days to withdraw from an online purchase. Digital content is an exception: if you ask for immediate access and acknowledge that you lose the right of withdrawal, that right ends once access begins. You are asked to confirm this at checkout.
Where that confirmation was not given, the 14-day right applies as normal.
Withdrawal and refund requests are handled by Lemon Squeezy as the seller of record. You can also write to us and we will help.
Refunds
If the product does not work (the key fails, the page will not load, you cannot reach the questions), tell us and we will fix it. If we cannot, we refund you.
We cannot refund on the grounds that you did not pass the exam. See the next section.
What this is not
These are independent study materials. They are not affiliated with, endorsed by, or sourced from Google, Amazon Web Services or Microsoft, and they are not official preparation products.
The content is written from each certification's publicly available exam guide: its sections, their weightings and the services listed in them. No live exam content is reproduced. Publishing real exam questions breaches the certification agreement of the provider concerned and gets candidates barred, which is why you will not find any here.
No result is promised. Doing well in a Study Kit does not mean you will pass the certification. The marker shown on your results is a working target used by study programs, not a threshold set by the certification provider.
Product names are trademarks of their respective owners.
