How our AWS practice questions are made

  • Every question is checked several times, and together they follow the real exam's domains and topics. We work in two stages: first we plan what each topic has to test, then we write, judge and audit the questions, and AWS professionals review most of them.
  • You could ask ChatGPT or another AI chatbot for a full set of practice questions, but nothing plans them against the exam or checks them. If that were enough, we'd do it ourselves and skip everything below. We know exactly what these models do: even the strongest make a lot of mistakes that sound right. That's why we built a whole system around them.

1. What each topic has to test

  • Planning comes first, because a question is only as good as what it sets out to test. Two engines work in a loop on what each topic has to test, and a plan that fails review is planned again.
  • Only then does writing start. Quality control follows the exam's domains and topics, and watches for gaps, duplicates and hallucinations.

Our process is part human, part AI.
  • Our own engines on the latest GPT-6 model family write and judge each question in a loop. A question only goes on once they agree on what is correct and what is not.
  • The questions are then audited by different models from Anthropic. Most are then audited again by AWS professionals. Some of the questions come from learners themselves.

This takes a lot of time and care.

AWS practice exam FAQ

What is the AWS Exam Simulator?

A realistic testing environment with a large database of practice questions, timed exams, performance tracking and explanations for correct and incorrect answers.

Can I pass the AWS Certification Exam by only doing practice exams?

Yes, for many learners dedicated practice can be enough: realistic practice exams strengthen your knowledge and find your weak areas. Hands-on experience and a good grasp of the foundations help too.

What are the two modes: Practice and Exam?

The simulator offers two modes: Practice Mode and Exam Mode. In Practice Mode, you can see hints, explanations, and access question reviews as you answer. In Exam Mode, the experience mimics the real AWS exam, with timed sessions and no immediate feedback, helping you gauge your readiness under real test conditions.

How long does it take to be ready for the official exam?

Preparation time varies depending on your background and the AWS certification level. Typically, a focused preparation of 1 to 3 months with regular practice exams, review of weak domains, and additional study of core concepts is effective for most candidates.

Can I just use ChatGPT for AWS practice questions?

You can, and the questions will sound right. But a chatbot doesn't plan them against the exam's domains and topics, and nothing checks them, so some can be wrong without you noticing. If one prompt were enough, we'd use it ourselves. We pay for the strongest models, and even they make a lot of mistakes. So ours go through a whole process: we first work out what each topic has to test, then every question is written, judged and audited, and AWS professionals review most of them.
