DAT Quantitative Reasoning study guide
DAT Quantitative Reasoning · Work through your exam, one topic at a time.
The Dental Admission Test (DAT) is the admissions exam accepted by all U.S. dental schools and select Canadian dental schools. It is designed to give dental education programs a means to assess an applicant's potential for success, and each school decides for itself how much weight to place on DAT results alongside the rest of the application. The test is delivered in English as multiple-choice items across four sections: Survey of the Natural Sciences, Perceptual Ability, Reading Comprehension, and Quantitative Reasoning. Topics on this exam: Survey of the Natural Sciences, Perceptual Ability, Reading Comprehension, and Quantitative Reasoning. The DAT Quantitative Reasoning study guide has 4 sections and about 1,533 words.
01Survey of the Natural Sciences: DAT Study Guide
The Survey of the Natural Sciences (SNS) is a 100-question, 90-minute section split into Biology (40), General Chemistry (30), and Organic Chemistry (30). It rewards broad, accurate recall and fast application of first-year science, not lab technique or research design. Biology: membrane transport and osmosis, enzyme kinetics (Km, Vmax, inhibition), Mendelian and molecular genetics, DNA replication/transcription/translation, cell cycle, major organ-system physiology, hormone feedback, evolution mechanisms, and population ecology. General chemistry: dimensional analysis and limiting reagents; gas laws; thermochemistry (ΔG = ΔH − TΔS); equilibrium and Le Chatelier; acid-base/pH and buffers; kinetics; electrochemistry; solutions and colligative properties.

The Perceptual Ability Test (PAT) is 90 questions in 60 minutes, with six 15-question subtests: apertures (keyholes), top-front-end (TFE), angle ranking, hole punching, cube counting, and pattern folding. It measures spatial visualization under strict pacing; no science content is tested. Apertures: a 3D object must pass through a matching opening. Eliminate choices by unique features-sloped edges, protrusions, and proportions-then rotate mentally.

Reading Comprehension (RC) is 50 questions in 60 minutes, usually built from three passages with about 15–17 questions each. Passages come from natural sciences, social sciences, and humanities. The section tests literal comprehension, inference, tone, and the function of evidence-not outside knowledge. Stems often ask for the author's primary purpose or the function of a paragraph.

Quantitative Reasoning (QR) is 40 questions in 45 minutes. It tests algebra, geometry, trigonometry, probability and statistics, ratios, percentages, unit conversions, and data interpretation. Questions include standard multiple-choice and quantitative comparison (QC) formats, so both calculation speed and comparison logic matter. Most items are designed for quick setup rather than lengthy computation.
