BCO practice questions - frequently asked questions

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

The BCO exam spans 4 domains: Preliminary Examination and Evaluation Principles (16% of the exam); Fitting (23% of the exam); Fabrication (45% of the exam); General Care and Services (16% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Fabrication 45%; Fitting 23%; Preliminary Examination and Evaluation Principles 16%; General Care and Services 16%.

The BCO exam has 150 questions and is completed in 3 hours 30 minutes. Our timed practice mirrors that length and pacing, so exam day feels familiar.
