GMAT - Computer-Adaptive Testing Format

The GMAT is administered using a method known as computer-adaptive testing where the questions on the exam scale in difficulty based on whether you correctly answer each question or not. Basically, this means that each question on the exam is assigned to somewhere within one of three difficulty ranges, which are the easy or low difficulty range, average or medium difficulty range, and the hard or high difficulty range. The exam will start out by presenting you with a question at the average difficulty level and will then move to progressively harder questions as you correctly answer each question until you reach the hardest level of questions available. If you answer a question incorrectly, the next question you will need to answer will be easier and the questions will become progressively easier as you continue to incorrectly answer the questions on the exam until you reach the easiest level of questions available. However, the difficulty of the questions you answer correctly will affect your score as questions answered correctly at the higher difficulty ranges will receive more points than questions at the lower ranges. In other words, each question is weighted based on its difficulty so questions falling within the easy difficulty range will receive fewer points than questions in the average difficulty range and questions in the average difficulty range will receive fewer points than questions in the hard difficulty range.
