Frequently asked questions
Are these tools really free?
Yes. All six tools on this page are free to use, with no account or sign-up required. They are separate from the CertGrid practice exams, which have a free daily sample and a paid plan for the full question bank.
Do I need a CertGrid account to use them?
No. Every tool runs entirely in your browser and does not save or send your inputs anywhere. You only need an account if you click through to practice questions and want your scores and history tracked.
How accurate is the Exam Readiness Calculator?
It applies a simple, transparent rule based on the numbers you enter (your recent score, your average, and how many timed mocks you have done) - it is an estimate to guide your study decisions, not an official prediction or a guarantee that you will pass the real exam.
Which exams are covered?
The Exam Readiness Calculator and Practice Score Calculator support a curated list of popular exams (AZ-900/104/305, SC-900, AWS CLF-C02/SAA-C03/SAP-C02, Security+, Network+, CCNA, CKA, Terraform Associate, GCP ACE, PMP) plus a manual "Other" option for any exam. The Certification Path Finder and the two domain-based readiness checkers cover specific certification tracks.
Is CertGrid affiliated with Microsoft, AWS, or any other certification vendor?
No. CertGrid is an independent practice platform. These tools and our practice exams are original and not endorsed by, or sourced from, any certification vendor.
