CAT DILR Strategy: How to Choose the Right Sets

Set selection wins DILR

In DILR, choosing which sets to attempt matters more than raw ability. A 99-percentiler often attempts fewer sets than a panicking 80-percentiler - but picks the right ones.

The first 5 minutes

Before solving anything, scan every set. Rate each: easy, doable, or trap. Start with the easiest, not the first.

Signs of a good set

• A clear, finite set of arrangements
• Numbers that close quickly (totals, constraints that fix values)
• Two or more sub-questions you can see a path to

Signs of a trap

• Open-ended conditions with many possibilities
• Heavy reading with little structure
• One question that depends entirely on cracking the whole puzzle

Bottom line: solve 3 sets fully, not 5 sets halfway. Selection is the skill DILR really tests.
