AIIMS INI CET Exam Pattern 2027: Sections, Marking, Timing

The INI CET exam pattern decides how you spend every minute of a three-hour paper. AIIMS, New Delhi, conducts the Institute of National Importance Combined Entrance Test (INI CET) twice a year for MD, MS, MDS, 6-year DM and 6-year MCh seats at AIIMS institutes, JIPMER, PGIMER, NIMHANS and SCTIMST. For the January 2027 session, the exam is scheduled for 1 November 2026.

The paper has 200 questions split into four locked sections of 45 minutes each, with one-third of a mark deducted for every wrong answer. This guide explains the section structure, marking scheme, question types, MDS paper, tie-breaking rule and how scores turn into percentiles. It also shows what the pattern means for pacing, guessing and accuracy, with worked examples you can apply in your mock tests.

INI CET Exam Pattern at a Glance

The format is the same for MD, MS, 6-year DM and 6-year MCh candidates, who all take the MBBS-based paper. MDS candidates take a separate BDS-based paper in the same format.

Section-Wise Structure and Timing

The 200 questions are divided into four parts. Each part appears on screen one by one and has its own 45-minute timer. AIIMS does not publish which subjects fall in which section, so expect questions from different subjects in every part.

How the Sectional Timer Works

• Only one section is open at a time: The other three sections stay locked while you work on the active one.

• Sections close automatically: When the 45 minutes end, the section is submitted on its own and the next one opens.

• No going back: You cannot return to a closed section to change or add answers, even if you finish a later section early.

• Unused time does not carry over: Finishing a section in 35 minutes does not give you 10 extra minutes in the next one.

Some older pages describe INI CET as a single three-hour paper where you can move freely across all 200 questions. That is no longer how the paper runs, so follow the current prospectus and practise with sectional timers.

INI CET Marking Scheme and Negative Marking

Every question carries equal weight, whether it is a one-line fact or a long clinical vignette with an image.

The marking scheme does not describe partial credit for multiple correct choice questions, so treat each question as all or nothing. Check the instructions on the official prospectus and on the exam screen before you start.

Does Guessing Pay in INI CET?

With four options and a one-third penalty, the numbers are simple to work out.

A blind guess neither helps nor hurts on average, but it adds risk. Once you can rule out one or two options with real reasoning, attempting the question becomes worthwhile. The key word is "confidently": eliminating options on a hunch does not change the odds.

Question Types in INI CET

The prospectus describes objective questions of varying types, including single correct choice and multiple correct choice questions. Previous sessions have also used several formats within these broad types.

INI CET is known for testing concepts in depth and for asking about recent guidelines and advances, so a correct option often depends on a detail that standard one-liners skip.

Subjects Covered in the Paper

AIIMS states that questions are based on the MBBS curriculum prescribed by the National Medical Commission. In practice, the MBBS-based paper draws from all 19 subjects: three pre-clinical (Anatomy, Physiology, Biochemistry), five para-clinical (Pathology, Pharmacology, Microbiology, Forensic Medicine, Community Medicine) and eleven clinical subjects, including Medicine, Surgery, Obstetrics and Gynaecology, Paediatrics and the short subjects.

AIIMS does not publish subject-wise weightage. Larger subjects naturally produce more questions, but every subject can decide a rank in a close field.

INI CET Exam Pattern for MDS

MDS candidates take a separate paper based on the BDS curriculum prescribed by the Dental Council of India. The number of questions, duration, sectional format and marking scheme are the same as the MBBS-based paper.

Result, Percentile and Tie-Breaking Rule

AIIMS declares the result as a list of qualified candidates with their rank and percentile. To be eligible for counselling, you must reach the qualifying percentile for your category.

Clearing the qualifying percentile only makes you eligible for counselling. The seat you get depends on your rank, category, choices and the seats available in that session. Past closing ranks are useful as a benchmark only.

Tie-Breaking Rule

When two or more candidates score the same marks, AIIMS has applied the following order in recent results:

1. Fewer wrong answers: The candidate with fewer negative (incorrect) answers gets the higher rank.

2. Age: If the tie remains, the older candidate is placed higher.

Worked Example

Candidate A attempts 170 questions, gets 140 right and 30 wrong. Score: 140 - (30 x 1/3) = 130 marks.

Candidate B attempts 190 questions, gets 145 right and 45 wrong. Score: 145 - (45 x 1/3) = 130 marks.

Both score 130, but Candidate A ranks higher because of fewer wrong answers. Candidate B attempted 20 more questions and gained nothing for it. This is the clearest reason to protect accuracy rather than chase attempts.

What the Pattern Means for Your Preparation

• Three wrong answers cancel one right answer: As the example above shows, fewer attempts with high accuracy can match or beat a larger number of attempts made with more guesses.

• Each section is a separate mini-exam: A tough section cannot borrow time from an easier one. Train yourself to accept a few skips in a hard section and move on.

• Under a minute per question is tight: Long vignettes and images eat time. Quick recall questions are where you build the buffer to handle them.

• Wrong answers also affect ties: Because fewer wrong answers break ties, careless attempts can cost rank even when marks are equal.

• Depth beats volume: Questions that test recent advances and fine distinctions reward conceptual revision more than memorising one-liners.

Section-Wise Time Management Plan

Use the same routine in every section so it becomes automatic on exam day.

Exam-Day Habits That Help

• Watch the section timer, not the total timer: The section clock is the one that ends your chance to answer.

• Reset after each section: A difficult first section does not predict the next one. Start each section fresh.

• Do not change answers without a reason: Change a choice only when you recall a specific fact that proves it wrong.

• Keep the admit card instructions in mind: Reporting time, permitted items and ID rules are printed on the admit card, released from 26 October 2026 for this session.

Practise in the Current Pattern

Knowing the pattern helps only when your practice matches it. Take full-length mocks with four locked 45-minute sections, and analyse each one on the same day: list wrong answers, slow questions and questions you skipped but could have solved. Track your accuracy and wrong-answer count per section, not only your total score.

The INI CET exam pattern rewards controlled accuracy within strict sectional limits. Confirm the latest instructions in the January 2027 prospectus on the official AIIMS examinations portal, and build your mock routine around the four-section format.
