So, this turns out to be a challenge for CAT aspirant for strategizing their CAT preparation 2017.

DILR section in CAT 2017 can be a Game Changer

This section is challenging for students but students can perform well here as compared to other sections. And those students, who can solve more questions from this section, have more chances of scoring high percentile as compared to others. As per the ability of the students, this section can either push your performance up or can lower it down, depending on which section is attempted in the given time limit. It is to be noted that the questions in data interpretation and logical reasoning consume more time thus it requires high speed and accuracy skills.

DILR section questions are in 4 to 5 question set which then are followed by a set of problem. These questions are supposed to be planned based on trickiness and completely problematic described in tabular or graphic forms. The other side logical reasoning questions are based on family, tree, seating arrangement, rows, directions, statements, arguments etc. These questions can be solved using a right strategy leading to better score.

What changes have been made in CAT data interpretation?

For four years (from 2010 to 2014), this section was combined with quantitative aptitude. And questions from this section used to be part of quant second where there are 10 MCQs. When IIM Ahmedabad held CAT 2015, it made changes. This section was separated and a separate section was introduced in the exam patter. This new section was named as Data Interpretation and Logical Reasoning. It was done to boost the diversity in the exam.

This section contained a total of 32 questions. This entire section is divided into two sub – section whereas data interpretation was given 16 questions and same portion is covered by logical reasoning. Thus both share 50% weightage. Moreover, this section contains both multiple choice questions and non – multiple choice questions.

Couple of years back, this section wasn’t that much focused on, because quantitative aptitude and reading comprehension were given more weightage. But now this section too has become as important as the other one. Being a challenging one, this fetches good score. Thus, one should never skip this section. The way quant and verbal sections are prepared, same attention should be given to this section as well, because your call from IIM depends not only on your overall performance but also on your percentile in every section which has to be balanced and high. If any student has scored 98 percentile in quantitative aptitude and 97 percentile in verbal and reading comprehension but he only hit 78 percentile in data interpretation and logical reasoning section, so that student won’t be considered by IIMs for invitation as they need at least percentile of 80 to 85 in each of the sections.

Preparation for data interpretation for CAT 2017 requires little extra efforts. Basically, if any student gives correct answers of 10 questions of this sub – section out of total 16 questions, his way to clearing this entire section is greatly cleared. The total time for this section is 60 minutes so there is enough time in hands to proceed and every question is attended with almost two minutes. You are required to be accurate with good speed. Again, it all depends on how well you have prepared. No doubt, with good preparation you can easily fair well.
