The DAT also includes the Reading Comprehension Test and the Perceptual Ability Test (PAT). There are six sections to the PAT, which require visual and mental dexterity. The PAT measures your ability to work with two- and three-dimensional objects, and be able to manipulate them visually and analyze them in different formats. The six sections are aperture passing, orthographic projection, angle discrimination, paper folding, cubes, and form development.
