CAT (Common Admission Test) is India's most prestigious and competitive MBA entrance examination, conducted annually by the Indian Institutes of Management (IIMs) on a rotational basis. First introduced in 1950 and moved to online format in 2009, CAT has evolved into the definitive gateway for aspirants seeking admission to the country's finest business schools. With over 3 lakh candidates appearing each year for roughly 5,000 seats across IIMs alone, CAT is one of the most competitive exams in the world — the acceptance rate at top IIMs hovers around 0.1%.
The examination tests three core competencies: Verbal Ability and Reading Comprehension (VARC), Data Interpretation and Logical Reasoning (DILR), and Quantitative Ability (QA). Each section is allotted exactly 40 minutes with strict sectional time limits, meaning a candidate cannot move between sections freely. The exam is computer-based and administered across three slots on a single Sunday in November. Questions are a mix of Multiple Choice Questions (MCQs) and Type In The Answer (TITA) format, with MCQs carrying a −1 penalty for wrong answers and TITA carrying no negative marking.
CAT scores are valid for one academic year and the percentile score — not the raw score — is used for shortlisting. The IIMs each have their own shortlisting criteria that go beyond percentile: they consider academic consistency (10th, 12th, and graduation scores), diversity factors, work experience, and section-level cut-offs in addition to the overall percentile. Getting a 99 percentile with poor academic performance in school can still result in no IIM call, while a 95 percentile with exceptional academics and work experience may fetch calls from Tier 2 IIMs.
Beyond the IIMs, CAT scores are accepted by over 1,200 institutions including FMS Delhi, SPJIMR Mumbai, MDI Gurgaon, NITIE, and the IITs. The exam is truly the cornerstone of India's MBA admissions ecosystem — with scores valid across virtually every top business school, it remains the single most important test an MBA aspirant will take in their life. Preparation typically spans 6 to 12 months of rigorous study, with most serious aspirants investing 3–5 hours per day in the final six months.

Clearing the CAT written test is only the first step. Shortlisted candidates are invited for a multi-stage selection process that varies by IIM but typically follows a similar structure. The Written Ability Test (WAT) — a 20-minute essay on a business, social, or abstract topic — tests communication and critical thinking. The Personal Interview (PI) is a 20–40 minute conversation that evaluates academic background, work experience, leadership potential, and clarity of purpose. Some IIMs have replaced WAT with group discussions or additional written exercises.
IIM Ahmedabad uses a unique AWT (Academic Writing Test) and a structured interview. IIM Bangalore's PI is known for being deeply analytical, testing both quantitative reasoning and managerial thinking. IIM Calcutta focuses heavily on academics and analytical depth. Newer IIMs give more weightage to the CAT percentile itself and less to PI, making the written test even more critical for them. Candidates are advised to thoroughly research each IIM's selection process and prepare accordingly — a strong 95 percentile with excellent PI performance can beat a 99 percentile with a weak interview at many IIMs.
The composite score used for final selection typically weighs the CAT score (50–60%), academic performance (10–20%), WAT (10%), and PI (20–30%). Work experience, gender diversity, and academic diversity (non-engineering graduates) often add bonus points. It is crucial to submit all required certificates, SOP documents, and reference letters by the deadline specified in each IIM's admission form, as missing paperwork can lead to disqualification even after a successful PI.
