What is the right strategy for preparing DILR for CAT?

Before moving on to the right strategy to improve DILR. You must know that there is no 'one' right approach or strategy to improve DILR. Every student has a different strategy of their own. However, here we will talk about the most popular strategy.
It revolves around two things -

  1. Time management- Optimising the utilisation of time is the major gameplay in this section of the exam. If you are able to manage your time and attempt the right questions accurately, you will be able to ace the exam.
  2. Question Selection- It is essential that you are able to select which sets to solve and which not. The sets in the exam are divided into easy, moderate and difficult. Hence, the selection of sets becomes a game-changer.

In the limited time, one must utilise the first few minutes (let's say 4 minutes) to skim through all the sets and note down what are the main topics of the sets.
Categorise them like (suppose)

  • Set-1: Seating Arrangement
  • Set-2: Knockout Tournament
  • Set-3: Miscellaneous
  • Set-4: Distribution etc.

Then decide the level of difficulty of each set as per one's own capability and finally move on to answer "What sets am I going to answer and in what order (from easy to hard)?"
This whole task shouldn't take more than 5 minutes. So, with an initial sacrifice of 5 minutes, a candidate has now strategised the next 35 minutes and the optimal course of action.
Now apart from choosing the right number of sets, one must keep in mind to solve one set, including all the questions, in 13-14 minutes max. This is more than sufficient time to solve all the sets chosen.
You should also try to include it in your mock tests and eventually set it according to your needs.
