DI & LR pattern in CAT 2010 so far
Arun Sharma, well known CAT expert, and author of many best selling CAT preparation books says, “The Data Interpretation and Logical Reasoning section in CAT 2010 till now has been calculation intensive.”
On the basis of the Day 4 of CAT 2010, Manish Saraf, PT Education mentioned that the questions in Data Interpretation and Logical Reasoning section were quite lengthy and data driven. “There were questions which had lot of data,” mentions Saraf.
Strategies for attempting the questions
According to CAT experts, the first thing to keep in mind while attempting the questions is to read the question properly. Not only do you have to study the caselet or the graph or the figures, but also check the questions which follow with respect to the number and the nature of the questions.
Arun Sharma mentions that the number of questions range from one to three for every caselet or graph or figure. Here Saraf mentions that if you see that there is only one question that follows a lengthy caselet or a data-driven graph or figure, then it is better not to attempt it. “Some of the questions are not worth attempting at the first go. It is better to keep them Marked for reviewing them later,” mentions Saraf.
In order to get the right cut off and a good sectional percentile, you should attempt the right questions. “If you see that there is one question after a massive data and which is calculation intensive, then leave it and proceed to next question. If you have sufficient time, then only you should come back to them,” Saraf suggests.
Preparing for DI & LR
With regards to preparation for the section, CAT experts advise that you should have good command over basic calculation skills. “You should know how to interpret various data formats. tables, line graphs, bar graphs, pie charts, flow diagrams and cumulative frequency tables. These are some of the data formats that have featured in CAT over the years,” says Byju Raveendran, CAT expert and founder of Byju’s CAT Classes.
He also mentioned that understanding and the ability to do percentage calculations is very necessary in order to crack questions. “You should have a very good idea of percentage calculations, comparison of fractions (to determine highest/ lowest percentage), average annual growth rates (CAGR) and related concepts like market share by value, market share by volume market share increase and decrease, etc.,” he adds.
“You should practice the methods of approximation and elimination. Approximation is the best tool to arrive at answers quickly but using it is an art, and you will have to learn this through trial-and-error and practice. Often you can arrive at the correct answer by the process of elimination,” Raveendran suggests.
For the lengthy questions, Saraf mentions that you should practice the art of reading. “You need to learn the art of reading so as to accumulate the data which you would require for solving the question.”
