Passage: While the general and subject tests are held at many undergraduate institutions, the computer-based general test is only held at test centers with appropriate technological accommodations. In the United States, students in major cities or from large universities will usually find a nearby test center, while those in more isolated areas may have to travel a few hours to an urban or university location. Many industrialized countries also have test centers, but at times test-takers must cross country borders.

large universities
