CAT (MBA) Exam Survival Guide

Window

National MBA entrance (computer-based) focused on speed + accuracy.
Sections:

• VARC (Verbal Ability & Reading Comprehension)
• DILR (Data Interpretation & Logical Reasoning)
• QA (Quantitative Ability)

Exam format:

• Total time: 120 minutes, with three locked sections of 40 minutes each (you cannot switch between sections once a section starts).
• Question types: MCQ + TITA (Type-in-the-Answer, no negative marking).
• Marking: +3 for correct, −1 for wrong MCQ, 0 for TITA or unattempted.

Must-do topics (80/20 focus)

• VARC (Verbal Ability & Reading Comprehension)
  • RC: main idea, author’s purpose, tone, inference vs detail, “according to the passage” evidence.
  • Para-summary, para-jumbles (build link pairs), odd-one-out.
  • Grammar only as it affects meaning clarity, not rule-memorisation.
• DILR (Data Interpretation & Logical Reasoning)
  • Set selection: quickly spotting doable sets.
  • Tables/grids, distributions, arrangements/sequencing, games/constraints.
  • Ratios/percentages and min–max reasoning inside sets.
  • Practice with mixed, multi-step sets that require progressive deductions.
• QA (Quantitative Ability)
  • Arithmetic: percentage, ratio, mixtures, time–speed–distance, work/rates.
  • Algebra: equations, inequalities, quadratics, absolute value basics.
  • Number systems: divisibility, remainders/mods, gcd–lcm.
  • Geometry/mensuration: triangles, circles, polygons, common areas/volumes.
  • Modern math: permutations & combinations, basic probability.
  • Progressions and simple functions (what happens when x changes, domain/range basics).

Top traps (avoid these)

• VARC
  • Picking options that “sound true” but don’t answer the question stem.
  • Extreme words (always, never, only) when the passage is moderate.
  • Scope shifts: options that go beyond what the passage actually covers.
• DILR
  • Trying to solve sets in your head instead of building a clean diagram/table.
  • Overcommitting to a bad set and refusing to bail.
  • Not marking derived constraints clearly, leading to repeated rework.
• QA
  • Forgetting to flip inequality signs when multiplying/dividing by a negative.
  • Squaring both sides and keeping extraneous roots.
  • Averaging percentages directly instead of using weights.
  • Losing track of units (km vs m, minutes vs hours, etc.).

Time split (per section – 40 minutes each)

• VARC (40 minutes)
  • Start with 2 medium RCs you can understand quickly.
  • Then 1 shorter RC.
  • Then para-jumbles / odd-one-out / summaries.
  • For 50–50 questions, mark once and move on; don’t re-fight the same item three times.
• DILR (40 minutes)
  • First 2–3 minutes: scan all sets.
  • Pick 2 clean sets that show clear structure after a couple of minutes of work and do them end-to-end.
  • Attempt a 3rd set only if time and clarity allow.
  • If after 6–7 minutes a set’s table/diagram is still unstable, bail.
• QA (40 minutes)
  • First pass: single-shot arithmetic and algebra questions you can do in under a minute.
  • Second pass: geometry and number theory.
  • Final pass: leftovers where you have a partial idea.
  • Don’t bleed more than ~90 seconds on one QA question.

(CAT uses fixed 40-minute windows per section. Plan inside each window rather than thinking of 120 minutes as one big pool.)

Last 48 hours checklist

• VARC
  • 4 timed RC sets: 2 science, 1 social science, 1 arts/philosophy.
  • For each passage: write a one-line “Main Idea” and note evidence lines for 3 tricky questions.
• DILR
  • 6 sets: 2 grids, 2 distributions, 1 games/constraints, 1 hybrid mix.
  • Enforce: draw diagram/table first, then systematically propagate constraints.
• QA
  • 80 mixed questions: ~40 arithmetic, 20 algebra, 20 geometry/number theory.
  • Maintain an error log tagged by trap: Sign / Units / Scope / Diagram / Concept.
• Mocks
  • 2 sectional tests (one DILR-focused, one VARC/QA).
  • 1 mini full mock (90–120 minutes) at exam-like time of day.
• Ring sheet (1 page cheat-sheet)
  • Key percent/ratio/TSD/work formulas.
  • Quadratic + discriminant conditions.
  • Basic mod rules and divisibility patterns.
  • A few combinatorics identities and probability frames.
  • A reminder for reading charts: Title–Axes–Units–Scale–Legend.

Quick facts & frames

• TAUSL for charts (DILR/RC graphs)
  • Title – Axes – Units – Scale – Legend: scan these before diving into numbers.
• RC assumption check
  • Answer must be supported somewhere in the passage.
  • Very extreme or emotional wording is usually suspect.
• DILR set selection rule
  • If 6–7 minutes in, you still don’t have a stable table with deductions, move on.
• QA sanity rules
  • Estimate a rough bound for the answer before detailed work.
  • Prefer ratios and relative thinking over heavy algebra when possible.
  • Write target units explicitly (km/h, litres, etc.).
  • Flip inequalities whenever you multiply/divide by a negative number.

Speed tactics

• Two-pass strategy inside each section
  • Pass 1: harvest all clear, quick gains.
  • Pass 2: come back to marked questions with leftover time.
• QA
  • Back-solve from options for equations/mixtures.
  • Plug simple numbers for ratio/percent questions instead of handling pure symbols.
• VARC
  • Narrow by scope and tone first, then decide between close options.
  • Don’t reread the whole passage for every single question; go back surgically.
• DILR
  • Keep diagrams neat and legible; redraw if they get messy.
  • Mark definite vs possible placements clearly.

Exam-day mini-plan

• Arrive early, sit, and do a 3-minute warm-up:
  • 2 easy QA single questions
  • 1 small grid / DI sketch
  • 1 short para-summary or inference.
• VARC
  • Start with a medium-difficulty RC you actually understand.
  • Leave the densest, most abstract RC for last.
• DILR
  • Aim to fully solve 2 good sets rather than half-solving 3.
  • Trust your set selection rule; don’t get emotionally attached.
• QA
  • Sweep arithmetic and basic algebra first; build momentum.
  • Mark 50–50s for one final return pass if time permits.
• Final 90 seconds in each section
  • Bubble/marking check.
  • Re-read any question stems that contain “EXCEPT”, “NOT”, or “FALSE”.
