What is INI-SS? This is an overview for new people who want to know about it.

INI-SS means Institute of National Importance Super Speciality Entrance Test. AIIMS New Delhi does this test two times in a year. They do it once for the January session, and the exam is usually in November. Once for the July session, the exam is usually in April or May.

This test is like a door to get into speciality seats in the best medical schools in India. These schools are all AIIMS campuses, PGIMER Chandigarh, JIPMER Puducherry, NIMHANS Bengaluru and SCTIMST Trivandrum.

You can think of INI-SS like the PG of super-speciality. But the competition is tougher, the subjects are narrower. Every question is very important.

I have taught residents. I have seen that people who do well in this test are the ones who study it like a subspecialty-depth test. They do not just study it like a PG entrance exam.

This test is online on a computer. It is all in English. If you want to get into AIIMS New Delhi or PGIMER Chandigarh, you have to do another test, Stage 2. This is like an assessment, and it is worth 20 marks. You do it on video.

INI-SS 2026 Exam Pattern. You need to know what you are up against.

Here is what you will face on April 25 2026.

• Stage 1 is a written test for all the schools. You get 80 questions. You have to answer them in 90 minutes. Each correct answer gives you 1 mark. Each wrong answer takes away one-third of a mark. If you do not answer a question, you do not lose any marks. You need to get at least 50 percent, 40 out of 80, to qualify for the next step. This is for schools that're not AIIMS. If you want to get into AIIMS or PGIMER, you have to do Stage 2.
• Stage 2 is like an assessment. It is for AIIMS and PGIMER. This test is worth 20 marks. You do it on video. It tests how well you can solve problems and how much you know about your department. Only people who do well in Stage 1 and who want to get into AIIMS or PGIMER get to do Stage 2.

The 45-Day Study Plan. Week-by-Week Breakdown

Here is a plan I have improved over the years of helping people who want to specialize. It works whether you are a doctor with a few hours a day or someone who can study full-time.

Week 1–2 (Days 1–14): Revision of Basics + Old Question Analysis

• Your 14 days should do two things. First, quickly go through the topics in your area of interest using short video resources. Don't try to read all the textbooks. You just need to understand the basics. Second, solve the 5-year-old questions from the INI-SS exam. This is very important. Analyzing questions shows you what topics are often asked and how deeply you need to understand the clinical issues.
• In my experience, 30–40% of INI-SS questions are either the same as before or similar to past papers. If you ignore questions, it's like not looking at a patient's medical history before treating them. You're missing out on useful information.
• Daily target: 4–5 hours of study. Two hours on topics, one hour on old questions, one hour on fixing weak areas.

Week 3–4 (Days 15–28): Deep Study + Focused Revision

• Now you know your weak areas from analyzing old questions. This is the time to study deeply. For those who want to do a DM in Medicine, focus on guidelines. Like AHA/ACC for heart issues, KDIGO for kidney issues and ILAE for brain issues. For MCh aspirants, learn the steps of operations, how to interpret images and staging systems.
• Spend at least 30 minutes a day practicing with images. INI-SS exams often have pictures, slides, X-rays and ECGs. You need to get used to interpreting these.
• Daily target: 5–6 hours. Three hours on topics, one hour on images, one hour on analyzing mock tests, and 30 minutes on updates on medicines.

Week 5–6 (Days 29–42): Mock Tests + Quick Revision

• This is where you can make or lose your rank. Use 60% of your study time for mock tests and analyzing them. Take a test every other day. 80 Questions in 90 minutes, like the real exam. No phone, no breaks and strictly timed.
• After each test, spend twice as much time analyzing your mistakes. Sort errors into three types: things you didn't know, things you knew but chose careless mistakes. I have seen that careless mistakes alone can cost 5–8 marks. And it's easy to fix.
• Daily target: 5–6 hours. Alternate between mock tests and focused revision of weak areas.

Days 43–45: The Final Stretch

• Stop learning things. This is the time for revision. Go through your notes. The ones you made from mock test mistakes and important old questions. Review topics: drug doses, updates, scoring systems like CHA₂DS₂-VASc and recent trials.
• Sleep well the night before the exam. I have seen many good doctors do poorly because they studied until 3 AM and went to the exam tired. Your brain remembers things when you sleep. Respect that.

Subject-Wise High-Yield Strategy

INI-SS is very specific to each branch. So your preparation must be customized. Here are the branches where I see a lot of exam activity with the topics that keep coming up:

DM Cardiology:

• Coronary syndromes. You need to know the difference between STEMI and NSTEMI management.
• Heart failure. There are two types. HFrEF and HFpEF. Make sure you know the 2023 AHA/ACC guidelines.
• Arrhythmia management is also important.
• Heart disease. When to intervene is crucial.
• Cardiac imaging. Echo measurements and cardiac MRI indications are frequently asked.
• Congenital heart disease questions are increasing. Tetralogy of Fallot and ASD/VSD haemodynamics are key.

DM Neurology:

• Stroke management. IV thrombolysis window and mechanical thrombectomy criteria per AHA 2019 guidelines are vital.
• Epilepsy classification. ILAE 2017 is what you need to know.
• Multiple sclerosis. McDonald's criteria are important.
• Movement disorders. Parkinsons drug ladder's frequently asked.
• Neuroradiology. MRI patterns in demyelination and infarct territories are yielded.
• Questions with images from Neurology are particularly important.

DM Nephrology:

• AKI staging. KDIGO criteria are what you need to know.
• CKD management. Target BP, anaemia correction with ESAs and mineral bone disease are crucial.
• Glomerulonephritis. Biopsy patterns are important. This is where Pathology residents have an advantage.
• Dialysis adequacy and transplant immunology basics are also key.

MCh branches:

Neurosurgery

CTVS

Surgical Oncology

Urology

Plastic Surgery

For these, focus on anatomy staging systems like TNM for relevant cancers, imaging interpretation like CT/MRI, emergency surgical decision-making and recent surgical technique updates.

The PrepLadder app offers structured question sets that mirror the clinical-vignette style of papers. This can help with topic- QBank practice aligned to INI-SS patterns.

Mock Test Strategy. When, How and How Many

Mock tests are essential. They are the most predictive factor of INI-SS success. Here is what works:

Quantity:

• Aim for at least 10–12 full-length mock tests in your 45-day window.
• That means one every 3–4 days in the first month, then every alternate day in the last two weeks.
• Quality of analysis is more important than quantity of tests.
• For every test, maintain an error log. Write down the topic, why you got it wrong and the correct reasoning.
• This error log becomes your valuable revision document in the final week.

Timing discipline:

Practice the 90-minute window. You have 67 seconds per question. That is tight.

Develop a strategy:

1. First pass (60 minutes). Answer everything you're confident about and flag uncertain ones.

2. Second pass (25 minutes). Return to flagged questions.

3. Last 5 minutes. Review marked answers, check for any questions.

Negative marking management:

• With −⅓ deduction per answer, blind guessing across 80 questions is statistically punishing.

My rule of thumb:

• Eliminate two options with confidence before attempting.
• If you cannot eliminate at least two, leave it blank.
• In practice we do not guess diagnoses. We eliminate differentials. Apply the logic here.

Common Mistakes That Cost Ranks

I have been watching students who want to be speciality doctors for 25 years now. I have seen the mistakes that make some students pass, and others fail. Here are the mistakes:

Mistake 1: Thinking INI-SS is the same as NEET PG. NEET PG checks if you know a little about subjects. INI-SS checks if you know a lot about the subject you chose. If you are studying General Surgery for a DM Cardiology seat, you are wasting your time.

Mistake 2: Not thinking about marks. Let us say you answer 70 questions and get 50 right. You will get 50 minus some marks for the answers. This means you will get 43.3 marks. If you answer all 80 questions and get 55 right, you will get 46.7 marks. If you answer 60 questions and get 52 right, you will get 49.3 marks. So it is better to answer the questions you are sure about.

Mistake 3: Not practicing with images. These days, the INI-SS exam has questions with images. This can be up to 18% of the exam. If you do not practice with images from radiology and pathology, you will lose marks.

Mistake 4: Not having a plan to study again. Just reading something once. Hoping you remember it is not how our brains work. You need to read something, then read it again after some time and then again after some time. This is called repetition. You should make a schedule for the 45 days and include time to study again.

Stage 1 vs Stage 2 — Preparation Comparison Table

Key points for the INI-SS 2026 exam

• The INI-SS exam is on April 25 2026. It has 80 multiple-choice questions. You have 90 minutes to complete the exam. It is a computer-based test. You will lose one-third of the marks for each answer.
• To qualify for the stage, you need to get at least 50 percent in the first stage. This means you need to get at least 40 out of 80. If you do well, you can go to JIPMER, NIMHANS, SCTIMST for counselling. You can also go to the stage at AIIMS and PGIMER.
• The next stage is like an interview. It is for 20 marks. You will be asked questions on a video call. This is for people who want to go to AIIMS and PGIMER.
• Many questions in the INI-SS exam are similar to questions from previous years. So it is an idea to go through old question papers.
• You will also get questions with pictures. These can be X-rays or pictures of patients. You should practice looking at these pictures every day.
• The people who make the exam often ask questions about guidelines. So you should know about the guidelines from AHA, ACC, KDIGO, ILAE and ESC.
• Sometimes the exam has questions. Two options may look correct. One is the old guideline, and the other is the new one.
• When you are not sure of the answer, do not guess. Only answer if you are sure about it.
• Taking tests is a good way to prepare. Try to take at least 10 to 12 full-length tests in 45 days.
• There are two lists of people who do well in the exam. One is the list for all INIs. The other is the list for AIIMS and PGIMER.
• You can find questions and practice tests on the PrepLadder app. This will help you prepare for the INI-SS exam.

Frequently Asked Questions About INI-SS 2026 Preparation

Q1: What is the difference between INI-SS and INI-CET?

INI-CET is for postgraduate admissions. Test your full MBBS syllabus. It has 200 questions. You get 3 hours. INI-SS is for -speciality admissions. It is focused on your subspecialty. Has 80 questions in 90 minutes. INI-CET is for MBBS graduates. INI-SS is for MD/MS/DNB holders.

Q2: When should I start preparing for INI-SS if the exam is 45 days away?

You should start preparing away. Make a plan for each week. In the first two weeks, revise your syllabus. Go through the previous year's questions. In weeks 3 and 4, focus on topics in your subspecialty. The last two weeks take tests and quickly revise everything. 4 Hours a day can be enough.

Q3: Is clearing the INI-SS Stage 1 enough for admission?

Yes, it is enough for some colleges like JIPMER and AIIMS. You need to qualify Stage 1 with 50% marks. Your rank also matters. If you want to get into AIIMS New Delhi or PGIMER Chandigarh, you need to clear Stage 2.

Q4: What kind of drug doses and scoring systems are commonly tested in INI-SS?

You should know doses like Alteplase for stroke. You should also know scoring systems like CHA₂DS₂-VASc for AF anticoagulation. The. Systems you need to know depend on your subspecialty. Pharmacology questions make up 10-15% of the test.

Q5: What is the strategy for managing negative marking in INI-SS?

Since you lose a third of a mark for each answer, don't guess randomly. Only answer questions when you can eliminate two options. Leave 8-10 questions you're not sure about. This can save you 2-3 marks.

Q6: How is INI-SS tested differently from what I studied in my MD/MS?

INI-SS tests your ability to make decisions. Questions are based on scenarios. You need to choose the next step or diagnosis. It's not just about recalling facts. You need to think like a super-specialist. Practice scenarios daily to improve your skills.

CLINICAL PEARL

When it comes to the INI-SS exam, the questions are not about what you know. The exam wants to know what you would do in a situation. So you should practice making decisions, not just memorizing things from a book.

In the twenty five years that I have been helping students, I have seen that the ones who use their experience working with patients to help them answer questions on the exam do better than the ones who just study books all the time.

Your time as a resident is very important. It is not a job, it is also a great way to learn and prepare for your exams.
