OAT Prep Book FAQ
The following answers to frequently asked questions about the Optometry Admission Test (OAT), studying for the OAT, and OAT test prep books can offer some helpful information as you decide on the best route toward studying for the exam.
Is the OAT a required exam?
The OAT is an exam that all optometry schools in the United States require their students to complete as part of the admission process.
The test covers several areas of study that optometrists need to learn before they begin their optometry careers. Therefore, the OAT provides a good indication of whether a student has successfully mastered each area before accepting them into the program.
Most optometry schools will consider your OAT score in addition to your admissions paperwork, essay, transcript, and other documents that denote your academic ability.
However, scoring higher on the scaled scoring system of 200 to 400 can benefit you and your application.
What subjects are included in the OAT?
The OAT covers four primary subject areas necessary for a deep understanding of the sciences and concepts that surround the field of optometry:
- Natural sciences
- Reading comprehension
- Quantitative reasoning
The natural sciences portion of the test includes biology, general chemistry, and organic chemistry, while the quantitative reasoning portion includes mathematical calculations and word problems.
Some OAT test prep books include study guides and sample tests for each area of the OAT. Others focus on only a singular subject, which could be beneficial for you if you need a little extra help in one area.
What’s the best way to study for the OAT?
Studying for the OAT is something students entering an optometry school should be serious about.
A motivated and dedicated attitude can help you succeed in the exam. Some students might find that an accountability partner can help them stay on track with their study goals.
The best way for you to study for the OAT could look different than ways other students choose to study.
Still, many students find that a test prep book dedicated to the OAT and its subject areas can be beneficial in the studying process.
These books provide you with informative material you’ll need to know for the exam while preparing you for the test with sample questions.
You can also supplement your studying with online courses and videos, written notes, or handmade flashcards, depending on your preferred way to study.
How long should I study for the OAT?
The length of time you should devote to studying for the OAT depends on several factors, including:
- Your learning style
- How quickly you pick up material
- How much time you have to spend on studying
- Whether you can devote specific blocks of time to studying
- Your study habits
You should prepare to spend at least several days per week studying for 3-4 hours per day for 2-3 months leading up to the exam.
You might even choose to begin 4-5 months ahead of time to ensure that you have extra time to review materials and study concepts you aren’t entirely confident in yet before taking the OAT.
What should I look for in an OAT prep book?
Some OAT prep books cover all four subject areas for the OAT, while others target specific subjects. If you want a general guide to the exam, you should choose a book with all the subject areas included.
If you have already studied for the exam but want to focus more on a specific subject area, a subject-specific book can help you do that.
Other key features to consider in an OAT prep book include:
- Sample questions and answers
- Practice tests
- Fair pricing
- In-depth instruction and study guides
- Study guides and practice tests from experts in the OAT
- Study and exam-taking tips from experts
Most test prep books don’t offer all of these features, but many do include several of them.
Can I use an old OAT test prep book to study?
The Association of Schools and Colleges of Optometry (ASCO) updates the OAT regularly to align with current best practices in optometry. Therefore, it’s important to use test prep books that reflect the most recent exam changes to subject matter and questions.
Test prep books you find in a library, or even some bookstores, could be outdated by several years. It’s best to look for a book with a publishing date or year within the last five years and even better if it’s within the last one or two years.
Do OAT practice tests reflect the actual exam?
If you purchase an OAT test prep book from an authoritative educational company that sources experts in the optometry field, you will likely find that the practice tests are similar to the actual exam.
What you shouldn’t expect is exact replicas of questions you’d find on the OAT in your practice exams.
Instead, you’ll see questions covering the material you’ve studied in similar ways as the questions on the real exam. They’ll test your knowledge and understanding of information and apply it to other concepts.
The practice exams in a test prep book should help you feel more confident in your ability to take the OAT.
How many times can I take the OAT?
There is no limit to how many times you can take the OAT.
However, you must wait at least 90 days before testing attempts. This waiting period gives you more time to study and review materials before you retake the OAT.
Colleges and universities will usually use your highest score out of any of the exams you take, even if your most recent score wasn’t your best.
Conclusion: The Best OAT Prep Book
We hope that this guide helps you find the best OAT prep book for you and your study habits to lead you to success with the OAT. However, it’s important to remember that you shouldn’t rely solely on the book for your study process.
An OAT test prep book can be an excellent study supplement as you prepare to take the OAT. You can also take advantage of online tests, library resources, and independent research and study guide creation to solidify your knowledge in each subject area.
