ROUB practice questions - frequently asked questions

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

The ROUB exam spans 7 domains: Keratometry (5% of the exam); Physics (16% of the exam); Biometry Instrumentation (11% of the exam); Instrument Settings for Biometry (13% of the exam); Examination Techniques for Biometry (18% of the exam); Sources of Error in Biometry (22% of the exam); Intraocular Lens Power Calculations (15% 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: Sources of Error in Biometry 22%; Examination Techniques for Biometry 18%; Physics 16%; Intraocular Lens Power Calculations 15%; Instrument Settings for Biometry 13%; Biometry Instrumentation 11%; Keratometry 5%.
