As far as commercially-available study aids, ICO does not endorse specific tools or
methods as many different modes of study work well for different applicants. However, we are
happy to provide information on a few of the options which past applicants have used:

OAT: Complete Preparation for the Optometry Admission Test
Format: book

Kaplan OAT
Format: book

Format: audio cassettes

OAT Professor
Format: online

OAT Flashcard Secrets

Most students also use their pre-optometry science coursebooks and class notes to study for the test and many have found MCAT preparation materials very helpful.

Some students use their first time taking the OAT as a “trial-run” just to see what the test is like.
We recommend that you use self-administered practice tests as your trial-runs – recreating the testing
environment and applying the same time limits as the actual test. This will help to ensure that you are
well-prepared, know how to pace yourself, and feel confident when you take the official test!
