CAT 2019 : Percentile Calculation Method Released by IIM Kozhikode
The Indian Institute of Management, Kozhikode has released the method for calculation of percentile which will be adopted in CAT 2019. It is to be noted that the CAT 2019 is scheduled to be held on 24th, November 2019. The last date of filling the application form is 18th, September 2019. The CAT exam is a completely computer based examination. The exam happens in two slots : Morning slot and Afternoon Slot at various designated centers across India. Below are the steps as released by the CAT authorities on their website: iimcat.ac.in .
Calculation of percentile score of a candidate:
The steps described below are followed to calculate the CAT 2019 overall and sectional percentile scores obtained by a candidate. While illustrating the percentile score calculation process, QA section is chosen as an example. Similar process is followed for the overall percentile score calculation and for the other two sections, i.e. DILR and VARC in CAT 2019.
Step 1: Calculate the total number of candidates (N) who appeared for CAT (i.e. including both morning and afternoon sessions).
Step 2: Assign a rank (r), based on the scaled scores obtained in the QA section, to all candidates who appeared for CAT. In the case of two or more candidates obtaining identical scaled scores in the QA section, assign identical ranks to all those candidates.
As an illustration suppose exactly two candidates obtain the highest scaled score in the QA section, then both of those candidates are assigned a rank of 1. Moreover, the candidate(s) obtaining the second highest scaled score in the QA section are assigned a rank of 3 and so on.
Step 3: Calculate the percentile score (P) of a candidate with rank (r) in the QA section as 
Step 4: Round off the calculated percentile score (P) of a candidate up to two decimal points. For example, all percentile scores greater than or equal to 99.995 are rounded off to 100, all percentile scores greater than or equal to 99.985 but strictly less than 99.995 are rounded off to 99.99 and so on.
A methodology similar to the one described above is used for the computation of the overall CAT percentile scores and for the percentile scores of other sections.
