Pattern of the test paper
CAT (as it is most commonly known across India) has evolved from a speed based simple test into a test which demands more proficiency in concepts and fundamentals rather than just speed.
Earlier CATs used to have 180 questions to be solved in 2 hours. The cutoff (minimum marks needed to get an interview call from the IIM) for such a paper was generally 20 each in the three sections (Mathematics + English + Data interpretation and Logic).
For the years 2001, 2002, and 2003 the paper consisted of 50 questions per section * 3 sections = 150 questions. The cutoffs were around 15 marks for individual sections and approximately 55 for whole paper.
CAT_2004
The first big surprise for CAT takers was in 2004, when the IIMs introduced the concept of differential marking for the first time. The paper had just 123 questions in three sections with the following distribution: (the decimal numbers are marks allocated to each question)
- English - Total: 50 (10 * 0.5 + 5*2.0 + 35 * 1.0) Cutoff - approx 12
- Mathematics - Total: 35 (15*2.0 + 20*1.0) Cutoff - approx 12
- DI (Data Interpretation) and LR (Logical Reasoning) - Total: 38 (12*2.0 +26*1.0) Cutoff - approx 17
Overall 123 Questions : 10 of half marks + 32 of 2 marks and 81 of 1 mark each. The overall cutoff for the paper was nearly 51-52 marks.
CAT 2005
CAT 2005 was an even bigger surprise. There were just 90 questions - 30 in each section. Each section was further divided into two subsections:
- Math
-
- Section 1A -10Questions of 1 mark each
- Section 1B - 20 Questions of 2 mark each
- The final Cutoff for this section was nearly 11
- English
-
- Section 2A - 10 Questions of 1 mark each
- Section 2B - 20 Questions of 2 mark each
- The final Cutoff for this section was nearly 15
- DI and LR
-
- Section 3A - 10 Questions of 1 mark each
- Section 3B - 20 Questions of 2 mark each
- The final Cutoff for this section was nearly 10
CAT 2006
CAT 2006, which was conducted on November 19, was a 2.5-hour exam instead of the traditional 2-hour exam. It is speculated that this change was made by the CAT exam committee to decrease the level of predictability of the exam and to relieve the stress caused to students in a two-hour time limit.
CAT 2006 had 75 questions, 25 questions per section and 4 marks per question, making it a 300-mark paper. There was a penalty of 1 mark for a wrong answer. The paper also proved to be a break from the previous pattern in that it had 5 answer options instead of the usual 4. The English section was generally perceived as very difficult, whereas the quantitative aptitude section was relatively much easier and basic than previous CATs as also in comparison to the other two sections.
CAT 2007
In 2007, the CAT exam was held on Sunday, November 18th. The exam had surprises for the past years for the changing pattern/number of questions etc. But this year the number of questions remained the same. There was 1 mark negative for each wrong answer. The duration of the test was 2.5 hours
Quantitative Ability
- 25 Questions each of 4 marks
- This is widely considered the toughest section this year
English
- 25 Questions each of 4 marks
- The reading comprehension part was tougher than that of last year
Data Intrepretation
- 25 Questions each of 4 marks
The solution key was published by various coaching institutes.
CAT 2007 results are published on IIM's CAT website as well as on SMS on Indian mobile phones by rediff.com's mobile short code 57333. More details can be obtained by sending an SMS "CAT" to 57333.
Notable incidents
In 2003, the CAT paper was leaked. This was a first in the 28 year old history of the test. A retest was held on 14th February 2004. Most news publications attributed the leak to logistical difficulties.
Besides the change in test format, CAT 2006 was also notable due to some printing errors that had crept into the question paper. The IIMs accepted the errors and formed a committee to look into the matter. The committee ruled that the wrong questions would be ignored. This leads one to a scenario where the different paper sets have a different number of "valid" questions. The difference will be made up by appropriately changing the denominator in the respective sets. For example, set 333 had 2 incorrect questions in quantitative ability. In this case a student scoring x/100 marks would now score (x/92)% marks. The idea of a re-test which was proposed by some quarters has been set aside by the authorities.
The results for CAT 2006 were declared on January 2nd 2007 among much confusion, as the server hosting the results was inaccessible for prolonged periods of time. Also, for the first time, the IIMs declared the actual key to the question paper along with the results.
here was a case of impersonation for the CAT 2007. Two persons tried to appear on behalf of the original candidates in chandigharh. The police arrested them on the day of the exam.


Newspaper reports in the year gone by have been rife with b-school placement stories of a rather disturbing kind. It appears that quite a few well-known business schools have been lying about their placement salary figures in public! Here's how you can see through the salary hype when you make that important admission decision.
