  Overview

The Common Admission Test (CAT) is the gateway exam for MBA and PGDM admissions at 21 IIMs and over 1,300 other B-schools across India, including several IITs and top private institutes. Each year, one of the six older IIMs conducts CAT on a rotational basis. For 2026, that responsibility falls to IIM Indore.

CAT 2026 will be held on Sunday, November 29, 2026, in three shifts, and the results are expected around the third week of December 2026. Everything else — your shortlist calls, interview rounds, and final admission — flows from how well you plan around this single Sunday.

A useful tip: the registration window looks generous at roughly six weeks, but most candidates rush in the final ten days, which overloads the server and increases the chance of payment failures. Filling your form in the first two weeks of August gives you a cleaner run and more time to fix errors during the correction window.

 Who Conducts CAT 2026

CAT rotates among the six original IIMs — Ahmedabad, Bangalore, Calcutta, Lucknow, Kozhikode, and Indore. IIM Indore is the conducting body for CAT 2026, which means the official website, helpdesk, and information bulletin all originate from IIM Indore, even though your scorecard will be accepted by all 21 IIMs.

 Eligibility Criteria for CAT 2026

Before you touch the CAT 2026 admission form, confirm you meet these requirements:

Educational Qualification

• A bachelor’s degree of at least three years from a university recognized under an Act of Parliament, or an equivalent qualification recognized by the Ministry of Education.
• Minimum 50% aggregate marks (45% for SC, ST, and PwD candidates).
• Final-year undergraduate students can also apply, provided they submit proof of degree completion by a specified date at the time of admission.
• Professional degree holders — CA, CS, CMA (ICWA), or Fellow of the Institute of Actuaries of India — are also eligible.

Age and Attempts

• There’s no minimum or maximum age limit for CAT.
• There’s no restriction on the number of attempts.

Nationality

• Indian nationals, NRIs, PIO, and OCI candidates can apply, but the exam is conducted only within India.

A practical example: If you’re currently in your final year of B.Com and expect your degree by June 2027, you’re still eligible to register for CAT 2026 — just be ready to submit your provisional/final degree certificate whenever the specific IIM asks for it during admission.

 CAT 2026 Admission Form

1. Visit the official website — iimcat.ac.in. Avoid third-party links; scams around exam season are common.
2. New Registration — Enter your name, email ID, and mobile number to generate your CAT ID.
3. Verify via OTP — Sent to both your email and mobile.
4. Log in using your CAT ID and password.
5. Fill personal details — Category, gender, nationality, and communication address.
6. Enter academic details — Degree, university, percentage, and year of passing.
7. Add work experience (if any) — Months of experience are counted till a specified cut-off date and can add marginal points in some IIMs’ composite score.
8. Select programme and city preferences — You can typically choose up to five preferred test cities; IIM Indore allots your final centre based on availability.
9. Upload documents — Photograph, signature, and category certificate (if applicable), each in the specified size and format.
10. Pay the application fee — Only online mode: debit card, credit card, net banking, UPI, or mobile wallets.
11. Preview and submit — Check every field twice before final submission.
12. Download the confirmation page — Keep both a digital and printed copy.

Small detail that trips people up: the fee is paid once, regardless of how many IIM programmes you select on the form — you don’t need to pay separately per institute.

 CAT 2026 Application Fee

The fee is non-refundable, so double-check your category and eligibility documents before making payment.

 Documents You’ll Need

Keep these scanned and ready before you start the form — this alone saves most of the time people lose during registration:

• Recent passport-size photograph (as per specified dimensions and file size)
• Scanned signature
• Category certificate (SC/ST/OBC-NCL/EWS/PwD), if applicable
• Educational mark sheets and degree certificate details
• Work experience certificate, if claiming experience points

Two timing rules deserve special attention this year: NC-OBC certificates must be issued on or after April 1, 2026, and EWS certificates must be valid for 2026–27, assessed against FY 2025-26 income. If your certificate is still in process, you can upload an undertaking along with your older certificate and proof of application — the CAT website hosts the undertaking format.

 Why the CAT Admission Form Matters

Many first-time applicants treat the form as a formality. It isn’t. Your city preference order, category declaration, and work experience entry directly influence:

• Which exam centre you’re allotted — popular cities fill up, and late registrants often get centres far from their preferred location.
• Your composite score components at several IIMs, where academic percentage and work experience carry weight alongside your CAT percentile.
• Your reservation benefits, which only apply if the certificate details match exactly what you declare.

Getting this right the first time avoids painful corrections later — the correction window is short (typically two to three days in October) and doesn’t allow every field to be changed.

 CAT 2026 Preparation:

You have roughly four months between the notification and exam day. Here’s how to use that time without burning out.

Phase 1: Foundation (August)

• Diagnose your strengths and weaknesses with one full-length mock test.
• Build a daily habit: one hour each for Quant, Verbal Ability & Reading Comprehension (VARC), and Data Interpretation & Logical Reasoning (DILR).
• Revise basic arithmetic, percentages, and grammar rules — these show up disproportionately often.

Phase 2: Skill Building (September)

• Move from concepts to timed sectional tests.
• Read editorials and long-form articles daily to strengthen RC speed and comprehension.
• Start solving previous years’ CAT papers under exam conditions.

Phase 3: Mock Test Intensity (October)

• Take at least one full-length mock every week.
• Analyze every mock in detail — where you lost time, which questions you should have skipped, and which topics repeatedly cost you accuracy.
• Track your percentile trend, not just your raw score.

Phase 4: Final Sprint (November, till Nov 29)

• Reduce new content; focus on revision and error-log review.
• Take 2–3 full mocks in exam-day conditions (same time slot, same break pattern).
• In the final week, taper down mock frequency and focus on mental rest, sleep, and exam-day logistics (admit card printout, ID proof, centre location).

Practical tip: Candidates who score 98+ percentile at older IIMs typically log 300+ hours of structured prep across these four months, with at least 15–20 full-length mocks. New IIMs generally have a lower cutoff band of 85+ percentile — useful context if you’re setting realistic targets rather than only chasing the top IIMs.

 Common Mistakes While Filling the CAT Form

• Uploading photos/signatures in the wrong format — leads to form rejection at the final step.
• Mismatched category certificate details — even a small spelling difference between your certificate and form entry can cause issues later.
• Selecting only one city preference — reduces your chance of getting a convenient centre if that city fills up.
• Ignoring the confirmation page — always download and keep it; it’s your only proof of successful registration.
• Waiting until September 14–15 to register — server load peaks in the last 48 hours, increasing failed transactions.
• Skipping the Information Bulletin — most eligibility and fee doubts are already answered there, in detail.

 Latest Updates and Trends for CAT 2026

• The exam continues to follow a computer-based format across roughly 170 test cities, one of the widest test-city networks among Indian entrance exams.
• CAT 2025 saw 12 candidates score a 100 percentile, reflecting the exam’s growing competitiveness as applicant numbers stay in the 2.5–3 lakh range annually.
• A single CAT score continues to be accepted by hundreds of MBA/PGDM programs beyond the IIMs, so one well-prepared attempt has wide-reaching value.
• Category certificate validity rules (NC-OBC and EWS) have tightened this cycle — a trend worth watching if you’re applying under reservation.

Key Takeaways

• CAT 2026 registration runs August 3 to September 15, 2026; the exam is on November 29, 2026.
• Minimum eligibility: bachelor’s degree with 50% marks (45% for SC/ST/PwD); no age or attempt limit.
• Application fee is ₹2,700 (general/OBC/EWS) or ₹1,350 (SC/ST/PwD), paid once regardless of programmes selected.
• Keep your photograph, signature, and category certificates ready and valid before you start the form.
• Admit cards release November 4, results are expected in the third week of December 2026.
• A structured four-month prep plan — foundation, skill-building, mock intensity, final sprint — beats last-minute cramming.

Conclusion

The CAT 2026 admission form isn’t just a registration formality — it’s the first strategic decision in your MBA application, from the exam centre you’re allotted to how smoothly your reservation benefits get processed. Register early, keep your documents ready in the correct format, and pair that with a disciplined, mock-test-driven study plan between now and November 29. Candidates who treat both the form and the preparation with equal seriousness consistently end up with more IIM interview calls — and fewer last-minute surprises.
