The CAT, like virtually all large-scale exams, utilises multiple forms, or versions, of the test. Hence there are two types of scores involved viz. raw score and scaled score.
The raw score is calculated for each section based on the number of questions one answered correctly, incorrectly, or omitted. Candidates are given +3 points for each correct answer and -1 point for each incorrect answer. There are no points for questions that are not answered. The raw scores are then adjusted, as necessary, through a process called equating. Equated raw scores are then placed on a common scale or metric to ensure appropriate interpretation of the scores. This process is called scaling.
Three scaled scores will be presented for each candidate: an overall scaled score and two separate scaled scores for each section. As the two sections evaluate 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.
