What Makes CAT DILR Challenging?

  • No fixed topic list
  • Lengthy caselets that require deep focus
  • Unpredictable set difficulty—some are easy, others are highly complex
  • Time management is crucial, as 1 difficult set can eat up 20+ minutes

That’s why the selection of the right sets is as important as solving them correctly.

How to Prepare for the CAT DILR Section?

  • Understand Set Types: Begin by solving basic DI and LR sets to become familiar with the types of problems presented.
  • Practice from Previous Year CAT DILR Papers: Solve at least 30–40 sets from the past 5 years to identify recurring patterns.
  • Build a Set Selection Strategy: Learn to judge which sets are worth attempting and which to skip.
  • Mix of MCQs & TITA: Practice both formats to improve speed and reduce dependency on options.
  • Sectional Tests: Time-bound free CAT mock tests help simulate exam pressure and improve speed.
