Optometry Admission Test (OAT) Practice Test

The OAT is a computer-based test comprising four sections: Survey of the Natural Sciences (Biology, General Chemistry, Organic Chemistry), Reading Comprehension, Physics, and Quantitative Reasoning. The test contains 200 multiple-choice questions and must be completed in approximately 4 hours and 5 minutes of testing time, plus a brief tutorial and optional breaks.

You may retake the OAT after a 90-day waiting period from your previous test date. You are limited to a maximum of four attempts in a 12-month period, and an individual may take the test no more than seven times total. All scores are reported to the schools you designate, so preparation between attempts is crucial.

You receive a separate scaled score for each of the four sections, ranging from 200 to 400, and an Academic Average score that is the mean of your scaled scores from the Natural Sciences, Reading Comprehension, and Quantitative Reasoning sections. The Physics score is reported but not included in the Academic Average. There is no penalty for guessing.

Competitiveness varies by program, but a strong Academic Average is typically 330 or above. Top-tier programs often have averages around 340-350. However, admissions committees use a holistic review process, considering your GPA, letters of recommendation, personal statement, and interview performance alongside your OAT scores.

It is strongly recommended to take the OAT at least one year before your intended matriculation date. For example, for Fall 2025 entry, take the exam by Summer/Fall 2024. This timeline allows scores to be verified and reported through the OptomCAS application service when it opens and provides a buffer for a retake if necessary.
