O-CAT practice questions - frequently asked questions

Plain answers about how O-CAT 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 O-CAT exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The O-CAT exam spans 8 domains: Evaluate platform corrosion system (17-22%); Testing Methods (16-21%); Safety (1-4%); Systems and requirements to collect information on platforms (12-17%); Types of oil platforms/rigs & equipment (1-3%); Primary corrosion protection systems (12-17%); Role of BSEE and A-B-C- grading system for reporting (1-4%); General Knowledge (24-28%). Every practice question on this site is tagged to one of these domains.

The O-CAT exam has 92 questions and is completed in 2 hours 30 minutes. Our timed practice mirrors that length and pacing, so exam day feels familiar.
