NBEO-Style Optometry Mock Test: 50 Applied Basic Science MCQs with Explanations

Last updated: November 2026

A 50-question practice test in the style of NBEO Part I (Applied Basic Science), for optometrists preparing for US licensure or advanced-standing OD programmes, and for B.Optom students who want to test their basic sciences.

• Format: four options, single best answer, 50 minutes.
• Coverage: Anatomy, physiology, neuro-ophthalmology, pharmacology, microbiology, pathology and optics, each applied to a clinical problem.
• After each answer: an explanation, a practical pearl and a link to the page that teaches the topic.

These are original practice questions written for revision; they are not NBEO questions and do not reproduce the official exam format or length. For eligibility and exam steps, see optometry exams abroad.

After the test
