Released CAT Data Interpretation and Logical Reasoning sets, filed by set type — standard and unconventional charts, caselets, data sufficiency, arrangements, games and tournaments, routes and networks — so you can practise the set types that break you.
One-time payment for one month. Nothing auto-renews.
Data Interpretation and Logical Reasoning is CAT's second section: 20 questions in roughly 40 minutes, arranged as four or five sets of four to five questions each. It is the section where set *selection* decides the score, because a badly chosen set can absorb fifteen minutes and return nothing. Prasnya files every DILR question from its 10 released slot papers under three chapters — Data Interpretation, Basic Logical Reasoning, and Advanced or Hybrid DILR — and then under the specific set type: caselets, data sufficiency, arrangements, games and tournaments, routes and networks, scheduling and allocation. Practising by set type is what makes the weakness visible, and because each set carries its full table, chart or passage with it, a set taken as a timed mock behaves exactly as it did in the paper.
20 questions in about 40 minutes, as four or five sets. Set selection matters more here than raw speed — the section rewards recognising early which set is tractable.
Data Interpretation & Logical Reasoning, as the catalog files it. Each chapter breaks down further into its own topics, and every one of them is a route you can practise or test on its own.
Standard charts, unconventional charts, mixed and missing DI, caselets, data sufficiency
Arrangements, deductive logic, ranking and order
Games and tournaments, set theory, routes and networks, scheduling and allocation
