DAT Practice Test 2026 — Free DAT Exam Prep Questions
The DAT is the admission test used by U.S. and Canadian dental schools. It covers the Survey of the Natural Sciences (biology, general chemistry, organic chemistry), Perceptual Ability, Reading Comprehension and Quantitative Reasoning. Our practice set follows the ADA's 2026 test specifications, including the updated organic chemistry topic names, with science problems, a science reading passage, math word problems and text-adapted perceptual items.
The number of patients at Kendall Dental Clinic grew by 10% in the first year, 20% in the second year and 30% in the third year. By what percent did the number of patients increase over the three years?
