What is a GRE CAT and how does it work?

A CAT is a computer-adaptive test, whose software calculates your score based on the number of questions you answer correctly, the difficulty of the questions you answer, and the number of questions you complete. When you take the GRE CAT, you'll begin each section with a medium-level question and a score of 500.

If you answer the question correctly, the computer will raise your score and give you a harder question. If you answer the question incorrectly, your score will decrease and you'll be given an easier question. The process repeats for each question in the section, to arrive at your final score for that section.
