How to Study for the OAT (2026 Guide): Study Plan, Free Resources and Best Materials
How to Study for the OAT — A Proven 2026 Guide
Preparing for the Optometry Admission Test (OAT) can feel overwhelming. With Biology, General Chemistry, Organic Chemistry, Physics, Reading Comprehension, and Quantitative Reasoning to master, many students aren't sure where to begin. Success on the OAT isn't about memorizing thousands of facts. It's about understanding concepts, practicing consistently, and using the right study materials. In this guide, Dr. Jim Romano explains a proven approach that has helped students prepare for admission to optometry school for more than three decades.
Throughout this guide, you'll learn how to build an effective study schedule, choose the right resources, avoid common mistakes, and prepare for every section of the OAT using the concept-based approach that Dr. Jim Romano has taught for more than 35 years.

What Is the OAT?
The OAT (Optometry Admissions Test) is a standardized exam required for admission to most optometry schools in the United States and Canada. It is administered by the Association of Schools and Colleges of Optometry (ASCO) and tests your knowledge across four major areas:
- Survey of Natural Sciences — Biology, General Chemistry, Organic Chemistry
- Reading Comprehension
- Physics
- Quantitative Reasoning
The OAT is scored on a 200-400 scale. A score of 300 is the national average, and most competitive optometry programs look for scores of 320 or higher.

How to Study for the OAT: A Step-by-Step Plan
Step 1: Know the Test
Before you open a single book, understand exactly what the OAT covers. Review the official ASCO content outline and note which sections carry the most weight. Biology and General Chemistry together make up the largest portion of the Survey of Natural Sciences section.
Step 2: Take a Diagnostic
Identify your strengths and weaknesses early. Work through a set of practice questions in each subject area and note where you struggle most. This tells you where to spend the most study time.
Step 3: Build a Study Schedule
Most students need 3 to 6 months of dedicated preparation to score competitively on the OAT. Here is a general framework:
- Months 1-2: Content review — Biology, General Chemistry, Organic Chemistry
- Month 3: Physics and Quantitative Reasoning
- Month 4: Reading Comprehension strategy and mixed practice
- Months 5-6: Full practice sets, timed sections, weak area review
Step 4: Master the Science Sections First
The Survey of Natural Sciences is the longest and most content-heavy section. Prioritize Biology, General Chemistry, and Organic Chemistry early in your prep. Use Dr. Romano's YouTube videos to reinforce concepts you find difficult.
Step 5: Do Not Neglect Physics
Physics is unique to the OAT (it is not on the DAT) and catches many students off guard. Cover optics, mechanics, waves, and electricity. Give yourself dedicated physics study time — do not leave it to the last week.

Step 6: Practice Under Timed Conditions
The OAT is a timed exam. Once you have completed your content review, practice answering questions under real test conditions. Time pressure is a skill — the more you practice it, the more comfortable you will be on test day.
Best OAT Study Materials
Serious OAT preparation requires exposure to difficult, exam-level questions. The OAT Destroyer was designed specifically for that purpose — to push your understanding beyond memorization and prepare you for the real exam. Unlike app-based tools, OAT Destroyer builds deep conceptual understanding that holds up under pressure on test day.

OAT Study Tips from Dr. Jim Romano
- Understand, don't memorize: The OAT rewards students who understand concepts deeply. Focus on the "why" behind every reaction and process.
- Review your mistakes: Every wrong answer is a learning opportunity. Understand exactly why you got it wrong before moving on.
- Watch video explanations: When a concept is not clicking from a book, a video explanation often makes it clear instantly. Use Dr. Romano's YouTube channel freely.
- Stay consistent: Two hours of focused study every day beats a 10-hour cram session on weekends. Consistency builds retention.
- Start early: The students who score highest on the OAT almost always started preparing earlier than they thought they needed to.
Frequently Asked Questions
How long should I study for the OAT?
Most students need 3-6 months of dedicated preparation. If your science background is strong, 3 months may be sufficient. If you need to rebuild foundational knowledge, plan for 5-6 months.
What is a good OAT score?
The national average is 300. Most competitive optometry programs look for 320 or higher. Top programs may expect 330+.
What subjects are hardest on the OAT?
Many students find Physics and Organic Chemistry the most challenging. Physics is unique to the OAT and requires problem-solving skills, while Organic Chemistry tests conceptual understanding rather than memorization.
Is the OAT harder than the DAT?
The OAT includes a Physics section that the DAT does not, which many students find challenging. Otherwise, the science content overlaps significantly. Students who have prepared for the DAT often find the OAT transition manageable.
Conclusion
Learning how to study for the OAT is the first step toward optometry school. With a solid study plan, free video lessons from Dr. Jim Romano, a free Biology PDF, and the OAT Destroyer for serious exam-level practice — you have everything you need to prepare effectively.
