Start testHow these OAT practice tests match the real exam
The real Optometry Admission Test (OAT) has 230 questions and a 245-minute time limit. Question types: All multiple choice. Survey of the Natural Sciences (Biology, General Chemistry, Organic Chemistry), Reading Comprehension (three scientific passages of about 1,000–1,500 words), Physics and Quantitative Reasoning. Some questions are unscored experimental items that look like scored ones. Each practice test here uses the same question formats, so you get used to how OAT questions are asked before test day.
The tests draw on every OAT content area, weighted like the official outline:
- Biology (about 17% of the exam)
- General Chemistry (about 13% of the exam)
- Organic Chemistry (about 13% of the exam)
- Reading Comprehension (about 22% of the exam)
- Physics (about 17% of the exam)
- Quantitative Reasoning (about 17% of the exam)
Use tutor mode to see the explanation after each answer, or timed mode to practise at real exam pace. Every answer comes with an explanation of why it is right and why the other options are wrong.
