OAT study guide
OAT · Work through your exam, one topic at a time.
The Optometry Admission Test (OAT) is a standardized admission exam used by optometry programs in the United States and Canada to assess readiness for professional study. It is intended for applicants preparing to enter a Doctor of Optometry program, typically after completing undergraduate pre-optometry coursework. The OAT study guide has 6 sections and about 1,745 words.
01Survey of the Natural Sciences - Biology
The OAT biology section samples cell and molecular biology, genetics, microbiology, anatomy and physiology, evolution, and ecology. Questions reward recall of specific structures and processes, but many items ask you to predict an outcome-for example, what happens when a transport protein is inhibited or how a mutation changes a protein.
327 words, about 2 min02Survey of the Natural Sciences - General Chemistry
This section covers stoichiometry, gas laws, atomic structure and periodic trends, thermodynamics, kinetics, equilibrium, acids and bases, electrochemistry, and solution chemistry. The exam favors multi-step calculations and conceptual comparisons, so track units and limiting reagents.
262 words, about 1 min03Survey of the Natural Sciences - Organic Chemistry
The OAT organic chemistry section tests structure and bonding, functional groups, nomenclature, stereochemistry, conformations, substitution and elimination, addition reactions, aromaticity, carbonyl chemistry, and IR/NMR/mass spectrometry. You need to connect a structure to its properties and to a plausible mechanism.
296 words, about 1 min04Reading Comprehension
OAT reading comprehension presents passages, often science-related but sometimes humanities or social science, and asks about main idea, explicitly stated detail, inference, vocabulary in context, and the author’s tone or purpose. The section rewards precise return-to-text behavior, not outside knowledge.
300 words, about 2 min05Physics
OAT physics covers mechanics, fluids, waves and sound, optics, electricity and magnetism, thermodynamics, and modern physics. Most items are one- or two-step applications of a formula, but conceptual questions about direction, sign, and conservation are common.
282 words, about 1 min06Quantitative Reasoning
OAT quantitative reasoning covers arithmetic, algebra, geometry, trigonometry, probability and statistics, and data interpretation. The math is not advanced, but the section is timed and deliberately includes distractors, so setup and estimation matter as much as calculation.
