CET practice questions - frequently asked questions

Plain answers about how CET Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real CET exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The CET exam spans 6 domains: Inspection, Testing, and Maintenance (43-49%); Repair and Recharge (6-12%); Installation (22-28%); System Design and Configuration (11-17%); Work Management (0% of the exam); Safety (11-17%). Every practice question on this site is tagged to one of these domains.

The CET exam has 83 questions and is completed in 2 hours 20 minutes. Our timed practice mirrors that length and pacing, so exam day feels familiar.
