OAT Prep: Sections & Practice
The OAT is the Optometry Admission Test used for US optometry-school admissions. Here's what its sections cover — the Survey of Natural Sciences (Biology, General and Organic Chemistry), Physics, Reading Comprehension, and Quantitative Reasoning — with realistic COSMIQ practice.
COSMIQ prepares you for the OAT and administers realistic full-length mock tests — it does not administer the official test.
