CAT DILR Strategy: How to Choose the Right Sets
By Prachi Priya Jha 15 June 2026

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.
