In Verbal Ability and Reading Comprehension, the passages were quite long. Still, candidates didn’t have to visit the passage, again and again, in order to answer the questions. There were no questions like the tone of the passage, word meanings etc. Questions based on critical thinking were more.

In Data Interpretation and Logical Reasoning, questions were moderate and some were lengthy, difficult, and tricky. Candidates who had prepared for the worst could able to attempt atleast 4 sets in the paper.

The major shock came from Quantitative Ability, with the difficult questions the number of attempts drastically decreased. The paper was dominated by Arithmetic, Geometry, and Mensuration. Candidates with 160+ marks could able to secure 99+%ile.

CAT is an only first step to study in B-school, further Written Ability Test (WAT), Group Discussion (GD), and Personal Interview (PI) takes place.

Last year, there were 20 candidates securing 100 percentiles. Of these, 2 were females and 3 were Non-Engineers. The trend of the score, of 99 percentiles, is also changing over the years. The score was 174/300, 156/300, 178/ 300 for 99 percentile in 2017, 2016, and 2015 respectively. So, just aiming at the pre-defined score is not enough to crack CAT.
