OAT Quantitative Reasoning case studies
OAT Quantitative Reasoning · Put your knowledge to work in context.
The Quantitative Reasoning (QR) section is one of the four multiple-choice tests in the Optometry Admission Test (OAT), the standardized exam used by optometry schools in the United States and Canada as part of their admissions review. Candidates are typically undergraduate students or graduates preparing to apply to a Doctor of Optometry program, and the QR score is reported alongside Reading Comprehension, Natural Sciences, and Physics, so a weak math result is visible to every school that receives the report. The OAT Quantitative Reasoning case studies are 5 cases and about 2,766 words.
