At different stages of the selection process, Application Rating (AR) score of an applicant will be used. An applicant's AR score is the sum of the rating scores A', B' and C' (Tables 2-4) based on their percentage of marks obtained in the 10th standard, the 12th standard (depending upon the stream, viz. , Science', Commerce' and Arts & Humanities') and the Bachelor's degree programme (depending upon the discipline) respectively. For different streams/disciplines, the equivalent ARs are arrived at by using a (sort of) percentile equivalence of the score distributions using previous year's CAT data.
