The perceptual ability test is an important component of the dental admissions test in both the American computerized version and the Canadian written version. The only way to do well on the perceptual ability test (PAT) is to do as many practice tests as possible. These 3 PAT practice tests contain 90 questions each with answers on Keyhole, Top/Front/End Views, Angles, Hole-Punch, Cube Counting, and Paper Folding. That’s 270 PAT questions for you to practice on!
