What IIM CAT really wants??

The IIM scaling model is as follows:
Section Scores = 0 to 150 Total Exam Score = 0 to 450

Four scaled scores are presented for each candidate: an overall scaled score and three separate scaled scores for each section. As the three sections evaluate three distinct sets of knowledge and skills, scores do not correlate across sections. A high score in one section does not guarantee a high score in another section. Percentile rankings are provided for each individual section as well as for the overall exam score.

The CAT exam was developed to accurately identify top performing candidates and that design makes use of a scaled score range of 0-450.
In order to appropriately identify the top performing candidates, the CAT exam was, by design, very difficult. As would be expected with the more difficult CAT exam, no candidate answered 100% of the items correctly and no candidate achieved the top theoretical score. The exam design accomplished the goal of identifying the top performing candidates who were, indeed, ranked at the top of the list.
If the exam were designed to be substantially easier, it would be theoretically possible for a candidate to achieve a score of 450. However, an exam constructed to be that easy would not serve the distinct purposes of the IIM.
