A Computer Adaptive Test (CAT) is tailored to the individual exam taker based upon his or her performance. Thus, every examinee will receive a completely customized set of questions during a CAT. Each CAT session begins with a question of pre-calculated difficulty and the selection of each subsequent question is based upon the current performance of the examinee; a higher current score results in the selection of a more difficult question and vice versa. In order to accommodate both high and low performers, a CAT must construct each exam session from a pool of questions much larger than the minimal set required by the specific exam’s format.
<u>**Our exclusive performance dependent question selection algorithm:**</u> Unlike other study-aids for computer adaptive tests, Our [simulated exam sessions](https://www.catprep.com/index.html) are generated using the same formula you will experience during an actual CAT. Our question pools consist of large sets of pre-ranked questions, enabling our simulators' to provide a truly adaptive test session that mirrors the actual exam's behavior by isolating a test taker's performance level through a gradual adjustment of question difficulty.
