OSA practice questions - frequently asked questions

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

The OSA exam spans 8 domains: Pre-Operative Preparation of the Patient (5% of the exam); Instruments (25% of the exam); Aseptic Technique (20% of the exam); Ophthalmic Anesthesia (5% of the exam); Surgical Procedures (27% of the exam); Surgical Complications (3% of the exam); Ophthalmic Surgical Pharmacology (10% of the exam); Minor Surgery (5% 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: Surgical Procedures 27%; Instruments 25%; Aseptic Technique 20%; Ophthalmic Surgical Pharmacology 10%; Pre-Operative Preparation of the Patient 5%; Ophthalmic Anesthesia 5%; Minor Surgery 5%; Surgical Complications 3%.

The OSA exam has 80 questions and is completed in 1 hour. Our timed practice mirrors that length and pacing, so exam day feels familiar.
