As per the Indian Institute of Management, “the CAT 2021 normalization process will adjust for location and scale differences of score distribution across different forms.” The first normalization process of CAT is done across different forms, then the scores are further normalized across different sections. Nowadays, the normalization process has become a common trend and is used in all entrance exams which are conducted in different slots/shifts.

CAT Exam Dates 2021

We all know that the national level CAT exam is the biggest entrance exam, hence every year more than 2 lakh candidates register for it. As per last year’s trends, we expect more than 2.3 lakh candidates will register for the CAT 2021 exam. To conduct the exam successfully and without altercation, CAT 2021 will be conducted on November 28 in three different shifts. Therefore, three different test forms shall be conducted in three test shifts.

Before filling the application form, candidates must be aware of the exam dates of CAT 2021 as it contains the start and end dates, admit card date, CAT 2021 exam date, and much more. As per the exam dates, CAT 2021 will be held on the last Sunday of November 2021 i.e. November 28, 2021. Given below is the schedule of CAT 2021 which can be checked by candidates for reference.

What is the CAT Normalization Process 2021?

The entrance exam of CAT 2021 will be conducted only in computer-based mode in three shifts i.e. morning, afternoon, and evening. Henceforth, to avoid any kind of discrimination, the Indian Institute of Management, Ahmedabad will follow the process of normalization for CAT 2021 which will change scale differences of score distributions across different forms.

The normalization process of CAT 2021 will be followed as an established practice that will compare the scores of candidates across different/various forms. The main purpose of the CAT 2021 normalization process will be that none of the candidates from either of the slots/ shifts get undue advantage or face disadvantages.

The scaled scores will then be converted into the CAT percentile. The shortlisted candidates (on the basis of CAT percentile) will have to appear for the selection process of IIMs, which will include Written Ability Test (WAT), Group Discussion (GD), and Personal Interview (PI) rounds.

Calculation of CAT Scaled Scores

Complete details related to sectional scores as well as overall scaled scores will be mentioned on the result of CAT 2021. The below-mentioned steps will be followed by IIM in CAT result 2021, to calculate the scaled score of each section. Let us look at an example of how the scaled score will be calculated for CAT 2021 -

Step 1: First the mean & standard deviation (SD) will be calculated of the raw scores in the DILR section for all candidates who will appear in the morning shift

  • Let Mean = M1

  • Let SD = S1

  • Hence, G1 = M1 + S1

Step 2: Similarly, the mean and the standard deviation (SD) of the candidates who will appear in the afternoon shift will be calculated from the raw scores in the same DILR section for all candidates.

  • Let Mean = M2

  • Let SD = S2

  • Hence, G2 = M2 + S2

Step 3: Now, calculate the mean and the standard deviation (SD) of the raw scores in the DILR section for all candidates who will appear in both morning and afternoon shifts.

  • Let Mean be M

  • Standard Deviation be S

  • Therefore, G = M + S

Step 4: Calculate the mean raw score in the DILR section of the top 0.1% of candidates who will appear in the first-morning shift. Denote the same by 𝑀1 0.1

Step 5: Similarly, For the top 0.1% candidates of the afternoon shift, calculate the mean raw score in the DILR section. Denote it by 𝑀2 0.1

Step 6: Now For the top 0.1% of candidates who will appear in CAT 2021 for both morning and afternoon shifts, calculate the mean raw score in the DILR section. Denote the same by 𝑀0.1.

A similar technique will be followed to calculate the scaled score of all three sections. i.e. Total scaled score = Sum of scaled scores of DILR, VARC, QA.

How to Calculate CAT Percentile 2021?

IIM Ahmedabad has released the percentile calculation method of CAT 2021. The rank obtained by a candidate will be termed as CAT percentile 2021. On the basis of the scaled score, the percentile of CAT 2021 will be calculated. It is imperative for candidates to understand how their CAT percentile 2021 will be calculated and ranks will be allotted to them.

Higher rank will be provided to those candidates who score more marks in all sections. If two candidates will score similar marks in the VARC section, then in such case both of them will be given Rank 1. The CAT 2021 percentile score will be calculated on the basis of a defined formula. After the formula is implemented, there will be a need to round off the calculated percentile score (P) of a candidate up to two decimal points.

The following steps will be used with regard to the calculation of the CAT 2021 percentile. For example sake, the QA section is chosen to know how CAT percentile is calculated and a similar process will be applicable to other sections.

Step 1: Calculate the total number of candidates (N) who appeared for CAT 2021 (i.e. including morning, afternoon, and evening sessions).

Step 2: Assign a rank (r), based on the scaled scores obtained in the QA section, to all candidates who appeared for CAT exam 2021. In the case of two or more candidates get identical scaled scores in the QA section, then the same rank will be awarded to all those candidates.

As an example, suppose 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:

  • 𝑃 = ( (𝑁−𝑟) 𝑁 ) × 100

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.

The method that is mentioned above is used for the computation of the overall CAT percentile scores and for the percentile scores of other sections.

CAT Composite Score Calculation

CAT 2021 composite score for each student will be calculated based on scaled CAT Score, marks of 10th and 12th standard, graduation score, gender diversity, academic diversity and work experience.

CAT Result 2021

IIM Ahmedabad will announce the result of CAT 2021 in the first week of January 2022. CAT 2021 result will contain details related to the personal details of candidates, sectional scores obtained, percentile, as well as total, scaled score, and percentile.

Candidates who will qualify will be called upon to take part in the further admission process. CAT scores are accepted not only by the Indian Institute of Management but various other top b-schools other than IIMs as well.
