ABO Initial Certification practice questions - frequently asked questions

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

The ABO Initial Certification exam spans 9 domains: Retina, Vitreous, and Intraocular Tumors (15% of the exam); Cornea, External Disease and Anterior Segment (13% of the exam); Glaucoma (13% of the exam); Lens and Cataract (12% of the exam); Pediatric Ophthalmology and Strabismus (11% of the exam); Neuro-Ophthalmology (10% of the exam); Oculofacial, Plastics, and Orbit (10% of the exam); Refractive Management and Optics (8% of the exam); Uveitis (8% of the exam). Every practice question on this site is tagged to one of these domains.
