questions

Before you start CKS

Is this course current for the CKS exam?

It follows the current CKS exam guide — all 7 exam domains, with the weights shown on this page, and was last updated April 2026.

How do I book the CKS exam, and what does it cost?

You book it directly with the exam provider. The official exam page lists the current fee, format, length and passing score, which can vary by country.

Is this an exam dump?

No. The lessons and quiz questions are written to teach the exam objectives, and every answer comes with an explanation. Real exam questions (“dumps”) break the exam provider’s candidate agreement and can cost you the certification.

How long does it take?

About 5 hours of lessons, videos and hands-on walkthroughs across 7 modules, plus a 50-question practice exam.

What’s free?

Module 1 in full — lessons, hands-on walkthrough and quiz — with no card required. Any paid plan (from $8.99/mo) unlocks all 7 modules and the practice exam, and starts with a 14-day free trial.
