Free OAT Practice Tests

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.
