Best OAT Prep Book


Which is the best OAT prep book to buy? These are the top recommendations.

To get certified as an optometrist, you will have to take the Optometry Admission Test, also commonly known as OAT. You have to pass the exam before applying to an optometry college or school. The standardized exam is administered to test your understanding and application of various optometry information.

All optometry schools and colleges in the US and the University of Waterloo in Canada require students who would like to enroll for a Doctor of Optometry program to have passed the OAT exam. Having a good OAT score will significantly increase your chances of getting accepted into optometry school.

The OAT is a high-stakes exam and most students find it stressful. However, if you are well-prepared, nothing should make you not ace the test. The extensive test comprises four sub-tests that cover Quantitative Reasoning, Physics, Academic reading comprehension, and Natural Sciences (Biology, Organic Chemistry, and General Chemistry).

So, how best can you prepare for the OAT exam?

If you are like most students, you are probably looking for the best OAT prep books and study materials you can lay your hands on. However, this can mean a significant investment. The good news is you do not need a tone of OAT study material to ace the exam. Just a handful of the best books will be fine.

Read on for the must-have OAT prep books.
