DAT Study Guide 2026–2027 — Redesigned Illustrated Edition | 200 Practice Questions

Prepare for every section of the Dental Admission Test with a complete, illustrated study guide aligned to the current ADA test specifications.

This 239-page digital guide reviews the Survey of the Natural Sciences (biology, general chemistry, and organic chemistry), all six Perceptual Ability subtests, Reading Comprehension, and Quantitative Reasoning, then gives you two 100-question practice tests with a detailed explanation for every answer.

WHAT'S INSIDE

• An overview of the current exam: order of sections, item counts, timing, the 200–600 score scale, registration, fees, and retest rules
• Biology: cell and molecular biology, diversity of life, all major organ systems, genetics, development, evolution, and ecology
• General Chemistry: stoichiometry, gases, solutions, acids and bases, equilibria, thermochemistry, kinetics, redox and electrochemistry, atomic structure, nuclear reactions, and laboratory skills
• Organic Chemistry: nomenclature, stereochemistry, aromaticity, IR and NMR spectroscopy, lab techniques, acid-base ranking, mechanisms, and multi-step synthesis
• Perceptual Ability: apertures, view recognition, angle discrimination, paper folding, cube counting, and 3D form development, each with the official rules and a worked visual example
• Reading Comprehension: comprehension and critical-thinking skills plus a passage strategy for three passages in 60 minutes
• Quantitative Reasoning: algebra, data analysis and sufficiency, quantitative comparison, probability and statistics, and applied word problems
• Study schedules (six-month, three-month, and one-month plans), FAQs, test-taking strategies, and additional resources
