Frequently asked questions
Is it really free?
Yes. All questions and features are available at no cost. You just need to create an account.
Are the questions the same as the real exam?
Our questions simulate the format and difficulty of official exams, but they are not leaked real questions.
Why is every mock exam unique?
Unlike other platforms where you memorize answer positions, CertLabs shuffles both the question pool and the order of answer choices (A, B, C, D) on every attempt, instantly adapting detailed technical explanations so you test real knowledge, not visual memory.
Can I practice without a time limit?
Yes. Practice mode has no timer and shows the correct answer instantly.
Are my results saved?
Yes. All your attempts are recorded in your profile with detailed statistics.
Why is it free?
I built CertLabs while studying for the AWS SAA-C03. What started as a personal study project has grown into an open, free multicloud platform covering 52 certifications across AWS, Azure, and Google Cloud with thousands of scenario questions and high-yield study tools.
