OAT Quantitative Reasoning Practice Test 2024 Untimed [Explanation] 40 Questions Answers. Try our free Optometry Admission Test (OAT) Quantitative Reasoning online quiz for better OAT test prep. The Quantitative Reasoning section of the OAT requires considerable outside knowledge, proficient test-taking skills, and strategic use of the calculator.

The Quantitative Reasoning section is the only section of the OAT that allows using a calculator. However, the calculator tends to be pretty time-consuming. As such, its value tends to be overestimated.

The Quantitative Reasoning section of the OAT is designed to test the math skills required in Optometry school. The area contains 40 multiple-choice questions; you will have 45 minutes to complete them. A basic on-screen calculator like the one below will be available only in this section. It can be opened by clicking the “Calculator” button at the bottom of the screen. The calculator can add, subtract, multiply, divide, and take square roots, percentages, and reciprocals.
