CAT answer key 2024 tomorrow; how are scores normalised?

NEW DELHI : The Indian Institute of Management (IIM) Calcutta will issue the Common Admission Test (CAT) answer key 2024 and CAT 2024 response sheet tomorrow, December 3. CAT 2024 answer key will be made available on the official website, iimcat.ac.in.

Once IIM CAT answer key is out, candidates will be able to calculate their probable scores and percentile using CAT score calculator and CAT percentile predictor . Students will also be able to challenge the provisional answer key by December 5.

CAT exam 2024 was held on November 24 for admission to Post Graduate Programmes in Management (PGPs) and Master of Business Administration (MBA) programmes offered by IIMs and participating B-schools. The CAT question paper comprised three sections - Verbal Ability and Reading Comprehension (VARC), Data Interpretation and Logical Reasoning (DILR), and Quantitative Ability (QA).

Since the exam was held in three slots, a normalisation process will be used to eliminate the differences in difficulty level of the sessions. The raw scores of candidates will be normalised and converted into scaled scores.

CAT 2024: Normalisation process

The step-by-step process to calculate the CAT scaled score and CAT percentile are given below.

Step 1 : Calculate the mean and standard deviation (SD) of the raw scores in a section for all candidates who appeared in slot 1.

Let Mean = M1 and SD = S1, and G1 = M1 + S1.

Step 2 : Calculate the mean and standard deviation (SD) of the raw scores in a section for all candidates who appeared in slot 2.

Let Mean = M2 and SD = S2, and G2 = M2 + S2.

Step 3 : Calculate the mean and standard deviation (SD) of the raw scores in a section for all candidates who appeared in slot 3.

Let Mean = M3 and SD = S3, and G3 = M3 + S3.

Step 4 : Calculate the mean and the standard deviation (SD) of the raw scores in a section for all candidates who appeared in the CAT 2024.

Let Mean = M and SD = S, and G = M + S.

Step 5 : Calculate the mean raw score in a section of the top 0.1% candidates in the morning session and denote it by M1 0.1

Step 6 : Calculate the mean raw score in a section of the top 0.1% candidates in the afternoon session and denote it by M2 0.1

Step 7: Calculate the mean raw score in a section of top 0.1% candidates in the evening session and denote it by M3 0.1

Step 7: Calculate the mean raw score in a section of top 0.1% candidates in the exam and denote it by M 0.1

In case XYZ is a candidate who appeared in the morning session and his/her raw score in a section is R. Then the scaled score of XYZ in that section, say ^R given by;

A similar methodology is applied for the calculation of scaled scores for all the sections. If this formula yields any scaled score of more than 100, it will be rounded down to 100.

The CAT percentile will be calculated as follows:

• ? = [(? − ?)/ N] x 100

where;

P = Percentile score

N = Total number of candidates who appeared for CAT 2024
