Taking an OAT practice test can help to both give you an idea of the type and difficulty level of Optometry Admissions Test questions as well as test your knowledge of learned material after studying. Unfortunately, there are not many sample tests of OAT questions that can be found online, especially those that are free.

We’ve created completely free practice tests for students that contain both answers and explanations for each question. New tests are constantly being made and will be added below when they become available.

We recommend that these tests are used as diagnostic exams to help you measure your progress as you begin your studies and preparation for the OAT. Take one before you begin your studies to see what topics you need to improve on and take the rest throughout your studying to measure the progress you’ve made to achieve the goals you’ve set for the OAT.

OAT Biology Practice Tests

The biology section of the OAT covers topics including cell and molecular biology, diversity of life, structure and function of systems, developmental biology, genetics, and evolution, ecology, and behaviour.

It comprises 40 questions within the survey of the natural sciences section of the OAT. Each practice question below includes 40 questions covering these topics, at a similar difficulty to what one can expect on the real exam.

The general chemistry section of the OAT covers topics including stoichiometry, gases, liquids and solids, solutions, acids and bases, chemical equilibria, thermodynamics and thermochemistry, chemical kinetics, oxidation-reduction reactions, atomic and molecular structure, periodic properties, nuclear reactions, and laboratory techniques.

It comprises 30 questions within the survey of the natural sciences section of the OAT. Each practice question below includes 30 questions covering these topics, at a similar difficulty to what one can expect on the real exam.

The organic chemistry section of the OAT covers topics including mechanisms, chemical and physical properties of molecules, stereochemistry, nomenclature, individual reactions of the major functional groups and combinations of reactions to synthesize compounds, acid-base chemistry, and aromatics and bonding:

It comprises 30 questions within the survey of the natural sciences section of the OAT. Each practice question below includes 30 questions covering these topics, at a similar difficulty to what one can expect on the real exam.

The quantitative reasoning section of the OAT covers high school-level math, excluding calculus. You are allowed to use a basic four-function calculator. The list of topics included in this section are: Mathematical Problems: algebra (equations and expressions, inequalities, exponential notation, absolute value, ratios and proportions, and graphical analysis); Data Analysis, Interpretation, and Sufficiency; Quantitative Comparison; and Probability and Statistics

It comprises 40 questions completed in 45 minutes. Each practice question below includes 40 questions covering these topics, at a similar difficulty to what one can expect on the real exam.

The quantitative reasoning section of the OAT covers Units and vectors, linear kinematics, statics, dynamics, rotational motion, energy and momentum, simple harmonic motion, waves, fluid statics, thermal energy and thermodynamics, electrostatics, D.C. circuits, and optics.

It comprises 40 questions. Each practice question below includes 40 questions covering these topics, at a similar difficulty to what one can expect on the real exam.

As we continue to expand our question banks updates will be made to this website page. In addition to this, we will continue to add new sections to this page such as those covering the topics of reading comprehension, physics, and quantitative reasoning.
