The DI section in CAT can be rewarding but also your downfall if not attempted carefully. In today's article we outline some strategies that you could use to make sure that you attempt DI correctly. We have also added a smaller section on how to study for DI in the last month of preparation.
Strategies for Cracking DI
Selecting the Right Sets
Most of the times, your performance in the DI section depends on your ability to choose the right sets. In a CAT DI section, not all sets are worth attempts. There is a good spread of easy and difficult sets. The objective is to choose the easy sets and avoid the tough and time-consuming ones. What is also important is to prioritize the sets that you have chosen to solve so that you don’t end up spending too much time on any one set.
How does one select or reject a set on the face of it? There are many factors that can decide this.
1. Familiarity with the Data Representation
Sometimes the CAT examiners represent the data in a format that may be unfamiliar to you. Because of this there would be a big risk to attempt such a set as you never know how much time you might end up spending in deciphering it.
Here is a CAT 2008 set to illustrate the same:
2. The Nature of the Data Values
Sometimes, your set may have data values that are big (4 digits and more) or values that are in decimals. Usually such values are not so friendly to calculate. Hence such sets should usually be avoided.
Here is a CAT 2003 (Nov) set that falls in the above category.
3. Ability to Extract Data Values from the Set
Some times that set may be familiar to us and the data values may also be friendly, however it may be difficult to extract the exact values from the set. Since we spend considerable amount of time in calculation, we better take the correct data values and calculate. Again it is better to ignore such sets.
The following CAT 1999 set is a good example of this.
