What the Course Entails and Exam Details

Preparing for the OAT requires a comprehensive review of undergraduate-level science and mathematical concepts.

The examination content is divided into four primary sections:

• Survey of the Natural Sciences: This massive section covers Biology (cell and molecular, diversity of life, genetics, evolution), General Chemistry (atomic structure, bonding, states of matter, equilibrium, kinetics), and Organic Chemistry (mechanisms, synthesis, reactions).

• Reading Comprehension: This section assesses your ability to read, comprehend, and analyze scientific and professional passages. You will answer questions based on the provided texts.

• Physics: You will be tested on classic and modern physics concepts, including mechanics, thermodynamics, electromagnetism, optics, and nuclear physics.

• Quantitative Reasoning: This section measures your mathematical skills, covering arithmetic, algebra, geometry, trigonometry, and probability and statistics.

What to Expect in the Final Exam

The OAT is a computer-based standardized test administered under strict security conditions.

You should expect a marathon session, as the total testing time is nearly five hours, including an optional break.

The final exam structure generally follows this format:

• Total Time: Approximately 4 hours and 40 minutes, including optional tutorials and a 30-minute break.

• Format: The entire exam consists of multiple-choice questions within the four specified sections.

• Scoring: Each section is scored on a scaled range from 200 to 400.

• Passing Score: There is no universal "passing" score. Each optometry school sets its own benchmarks for competitive scores based on their applicant pool, though scores above 300 are generally considered average nationally.

How to Study and Exam Centers

Effective OAT preparation requires a structured, long-term study plan, usually spanning several months.

Actionable Study Strategies:

1. Diagnostic Test: Start with a full-length, timed practice exam to identify your weak areas immediately.

2. Structured Content Review: Use specialized OAT prep books and online courses to systematically review the science and math content.

3. Active Practice: Don't just read; solve hundreds of practice questions. Use flashcards for Biology and Chemistry terms.

4. Timed Practice Exams: Take multiple full-length practice tests under realistic timed conditions to build stamina and master pacing.

Exam Centers and Registration:

You must register for the OAT through the official Association of Schools and Colleges of Optometry (ASCO) website.

The OAT is administered year-round at specialized Prometric Testing Centers throughout the United States and Canada. After registering, you will schedule your specific appointment at a physical Prometric center convenient for you.
