IISER Cutoff Marks for IAT 2026

The IISER Cutoff Marks for IAT 2026 are split by category: General (UR), OBC-NCL, SC/ST, and EWS. The IAT is scored out of 240 marks, and past data shows cutoff scores are quite high.

Can I get IISER with 60 marks?

No, a score of 60 out of 240 in the IAT is very unlikely to secure admission, especially for General category candidates. A score below 60 would likely put a candidate beyond rank 2000.

Here is the expected marks versus rank analysis for IISER.

Is IISER better than IIT?

IISER focuses on science research, while IIT focuses on engineering technology and applied sciences. The choice depends on individual goals and preferences.

IISER Application Form FAQs

1. Can I select my preferred IISER campus while submitting the application form?

Yes. Candidates must rank their preferred IISER campuses when applying. Final allotment depends on IAT scores and seat availability, but preferences are considered.

2. I am a Class 12 student. Am I eligible to apply for IISER IAT 2026?

Yes, students appearing for Class 12 board exams in 2026 are fully eligible. Selected candidates must submit proof of passing, like the Class 12 marksheet, during admission.

3. Is there any limit on the number of times I can appear for the IAT exam?

Yes. Candidates may appear for the IISER Aptitude Test a maximum of three times consecutively in a year. Those who have appeared more than three times are not considered.

4. Should I send any hard copies of documents by post after completing the form?

No, the entire IISER 2026 application process is online. No hard copies need to be posted. Keep the originals for counselling and admission.

5. What if my name or details are printed wrong on the admit card?

Admit Card Errors

If you notice an error in your admit card after it is released, contact the IISER admission helpdesk immediately using the official contact details. Errors can usually be corrected before the exam date if you raise them in time.

Payment Failure During Application

If your payment fails or is pending, your application will be considered incomplete. Log in again to check your payment status, and if needed, make the payment once more to complete your submission.

Eligibility for IAT Without All Four Subjects

Yes, you can attempt the IAT even if you did not study all four subjects. You must have studied at least three of the four subjects—Physics, Chemistry, Mathematics, and Biology—in Class 12 to be qualified.

The IAT exam tests you on all four subjects. If one subject was not part of your course, prepare for it in advance.

• Physics
• Chemistry
• Biology
• Mathematics

What is IISER IAT Cutoff 2026?

The IISER IAT Cutoff 2026 is the lowest closing rank at which a seat is offered at a given campus. It is not a fixed qualifying score. The cutoff is decided by the IISER Joint Admissions Committee (IISER-JAC) and depends on seats available, candidate ranks, and the choices students fill during counselling.

There are two types of cutoffs. The eligibility cutoff is the minimum Class 12 score needed to apply — 60 marks per 100 aggregate for General category and 55 marks per 100 for reserved categories. The admission cutoff is the closing rank in each counselling round. Clearing the eligibility cutoff only qualifies you for counselling; actual admission depends on your rank falling within the closing rank of your chosen campus in that round.

IISER offers only one programme: the 5-year BS-MS Dual Degree in Sciences. There are no branch-wise cutoffs at admission. You choose your major (Physics, Chemistry, Biology, Mathematics, Earth Sciences) in your second or third year on campus.

IISER IAT Cutoff 2026: Important Dates

The IAT 2026 exam was held on June 7, 2026. Over 1.86 lakh students appeared for 2,343 BS-MS seats across all seven campuses.

Source: IISER Admission Portal – iiseradmission.in (Official Seat Allotment PDFs)

The General category closing rank at IISER Pune rose by 1,137 ranks from 2022 to 2025. IISER Berhampur’s final round closing rank moved from about 3,200 in 2022 to 8,789 in 2025. That is a shift of about 5,589 ranks over four years, reflecting growing student acceptance of the newer campus.

IISER IAT 2026 Cutoff: Common Questions

Will the IISER IAT 2026 cutoff be higher or lower than 2025?

IAT 2026 had about 1.86 lakh candidates, fewer than the 2.5 lakh who appeared in 2025. Fewer candidates can ease competition slightly. But cutoff direction also depends on paper difficulty. If the 2026 paper is harder than 2025, closing ranks could ease toward 2024 levels. A General category final round closing rank of 1,500 to 2,000 for IISER Pune is a reasonable estimate for 2026.

Is there a separate cutoff for the JEE Advanced channel at IISER?

Yes. Students who qualify JEE Advanced can apply through the JEE Advanced channel. These candidates are ranked separately and allotted seats from a reserved intake at each campus. The JEE Advanced channel closing ranks differ from IAT channel closing ranks. Both are published on iiseradmission.in after each allotment round.

IISER IAT Cutoff 2026: Important Dates

The IISER IAT 2026 cutoff is released with each round of seat allotment, starting from Round 1 in July 2026. The table below places upcoming events first, followed by completed events. Keep checking iiseradmission.in for official updates.

IISER IAT 2026 Expected Cutoff: Campus-Wise and Category-Wise

The official IISER IAT 2026 cutoff has not been released yet. Once counselling begins, it will be published round-by-round on iiseradmission.in. The table below gives expected Round 1 closing ranks for 2026 based on 2025 counselling data and current exam conditions.

IISER IAT 2026 Expected Cutoff Ranks

The expected Round 1 closing ranks for IISER IAT 2026 are listed below. These figures are based on 2025 counselling trends and are not official.

The official 2026 cutoff will be published on iiseradmission.in after each round of allotment.

IISER Pune and IISER Kolkata fill up early and have the tightest closing ranks. IISER Berhampur and IISER Tirupati have much higher closing ranks in Round 1.

These two campuses stay open through more rounds than other campuses. If your General category rank is above 2,500, look at these two newer campuses closely.

IISER IAT 2025 Round-Wise Closing Ranks

Counselling at IISER runs across up to nine rounds. Closing ranks rise with each passing round at popular campuses.

Students who receive a seat may upgrade to a better campus in a later round. This opens up their original seat for candidates with higher ranks. The table below shows how closing ranks moved across three checkpoints in 2025 for the General category.

At IISER Pune, the closing rank moved from 355 in Round 1 to 1,671 in the final round. That is a shift of 1,316 ranks across nine rounds.

At IISER Berhampur, the closing rank grew from 3,299 in Round 1 to 8,789 in the final round. That is a shift of 5,490 ranks. If your General category rank is between 1,000 and 3,000, do not give up after Round 1. Many seats open up in Rounds 4 through 7.

Should I freeze my seat in Round 1 or wait for later rounds?

Freeze your seat if you are happy with the campus allotted in Round 1. Choose Float if you want to try for a better campus in the next round.

Floating is safe because you cannot get a worse seat than your current allotment. If your first preference is already allotted in Round 1, freeze it right away.

Factors Affecting IISER IAT Cutoff 2026

The IISER IAT cutoff is not fixed in advance. Several factors decide how tight or relaxed the closing ranks will be in 2026. Here are the key ones:

IISER IAT 2026 Cutoff: Factors That Affect Closing Ranks

Several factors decide the IISER IAT 2026 closing ranks. These include the number of candidates, paper difficulty, seat availability, category, admission channel, campus popularity, and counselling round.

• Total candidates appearing: IAT 2026 saw about 1.86 lakh candidates. This is fewer than the 2.5 lakh who appeared in 2025. Fewer candidates can ease the closing ranks slightly at all campuses.
• Paper difficulty: An easier paper means more students score high. This compresses the rank distribution and pushes closing ranks higher (harder). In 2025, the paper was noticeably easier than 2024, causing significant rank inflation. The 2026 paper’s difficulty is the biggest variable.
• Total seats available: IISER 2026 has 2,343 BS-MS seats across seven campuses. Any change in seat intake directly affects closing ranks. More seats generally means higher (easier) closing ranks.
• Category reservation: OBC-NCL, EWS, SC, ST, and PwD categories have separate merit lists. Reserved category candidates compete only within their own category. Their closing ranks are always lower than the General category at the same campus.
• Admission channel: Candidates admitted through the JEE Advanced channel are allotted from a separate intake pool. IAT and JEE Advanced channel candidates do not compete with each other. Each channel has its own closing ranks.
• Campus popularity: Older campuses like IISER Pune and IISER Kolkata attract the most first-preference choices from top-ranked students. This keeps their closing ranks low (harder to enter). Newer campuses like IISER Berhampur and IISER Tirupati see higher closing ranks because fewer students rank them first.
• Round of counselling: Closing ranks rise across rounds as students upgrade to better campuses. This releases seats for lower-ranked students in subsequent rounds.

IISER IAT Cutoff 2026: Marks vs Rank

The IAT 2026 exam has 60 questions for a total of 240 marks. Each correct answer gives 4 marks. Each wrong answer deducts 1 mark. Your rank depends on your total score. The table below shows approximate score ranges and expected ranks for IAT 2026, based on 2025 score distribution trends.

In 2025, the IAT paper was easier than 2024, causing severe rank inflation. A score of 130 marks placed students about 4,000 ranks lower than the same score would have in 2024. If the 2026 paper is harder, ranks at a given score may improve significantly from 2025 benchmarks.

This table is a planning guide based on 2025 distribution trends. Your actual rank will be on iiseradmission.in after the result. Always compare your official rank to the published closing ranks before finalising your choices.

IISER IAT Previous Year Cutoff Trends

More students appear for IAT every year, and IISER campuses are gaining recognition as top science institutions. These two forces have driven closing ranks higher every year from 2022 to 2025. The table below tracks the General category final round closing rank at IISER Pune and IISER Berhampur across four years.

The biggest single-year shift at IISER Pune happened in 2025, when the closing rank rose by 648 ranks. This came from a record 2.5 lakh candidates and a simpler paper than 2024. IISER Kolkata’s General category closing rank grew by about 1,400 ranks from 2022 to 2025. IISER Berhampur’s final round closing rank moved from about 3,200 in 2022 to 8,789 in 2025. That is a shift of about 5,589 ranks, reflecting growing student acceptance of the newer campus.

In 2026, with about 1.86 lakh candidates (down from 2.5 lakh in 2025), the pace of increase may slow. But the four-year trend suggests closing ranks will stay well above 2024 levels unless the paper is significantly harder.

Has the IISER Cutoff Been Rising Every Year?

Yes, the General category closing rank has risen at every IISER campus each year from 2022 to 2025. Growing student interest and more candidates appearing are the main drivers.

In 2026, fewer candidates than 2025 may slow the pace of increase. But unless the paper is much harder, closing ranks are unlikely to fall back to 2024 levels.

How to Check IISER IAT Cutoff 2026

The IISER IAT 2026 cutoff will be published as part of the seat allotment list after each round. Follow these steps to check it once it is released:

• Go to the official IISER admission portal at iiseradmission.in.
• Log in with your registered email ID and password.
• Click on the "Seat Allotment" or "Opening and Closing Ranks" section for the relevant round.
• Download the official PDF showing opening and closing ranks for each campus and category.
• Compare your rank to the closing rank of your preferred campus and category.
• Repeat after every round, as closing ranks change with each new allotment.

IISER IAT Counselling Process 2026

IISER counselling is conducted entirely online by IISER-JAC. There are up to nine rounds of seat allotment from July to September 2026.

Here is how the process works:

• Step 1 – Registration: After the result, eligible candidates register on iiseradmission.in and upload required documents. These include the IAT 2026 scorecard, Class 12 marks certificate, category certificate (if applicable), and photographs.
• Step 2 – Choice Filling: You rank all seven IISER campuses in order of preference. Your rank and your choices together decide your allotment. You can update choices before the locking deadline.
• Step 3 – Round 1 Allotment: IISER-JAC releases the allotment list with opening and closing ranks for each campus and category. This is the first official 2026 cutoff publication.
• Step 4 – Freeze or Float: Choose Freeze to lock your current campus. Choose Float to try for a better campus in the next round. Floating is safe. You cannot get a worse seat than your current allotment.
• Step 5 – Seat Acceptance Fee (SAF): Pay the SAF to confirm participation after each allotment. Missing the payment deadline removes you from the process entirely.
• Step 6 – Subsequent Rounds: The allotment-freeze-or-float cycle repeats for up to nine rounds. Closing ranks rise at popular campuses with each successive round.
• Step 7 – Campus Reporting: After freezing a seat, report to your allotted campus for document verification and admission formalities before the reporting deadline.

Many General category students ranked between 1,500 and 4,000 have secured seats in Rounds 4 through 7 in past years.

Total Seats Across IISER Campuses in 2026

There are 2,343 BS-MS seats across all seven IISER campuses for the 2026 cycle. IISER Pune and IISER Kolkata have smaller intakes relative to demand.

This is why their closing ranks are the tightest. IISER Berhampur and IISER Tirupati tend to have more seats available in later rounds.

IISER IAT 2026 Cutoff: Expected Trends

The IAT 2026 had about 1.86 lakh candidates, fewer than the 2.5 lakh who appeared in 2025. Fewer candidates can ease competition slightly.

Cutoff direction also depends on paper difficulty. If the 2026 paper is harder than 2025, closing ranks could ease toward 2024 levels. A General category final round closing rank of 1,500 to 2,000 for IISER Pune is a reasonable estimate for 2026.

Rising Cutoff Trend

The General category closing rank has risen at every IISER campus each year from 2022 to 2025. Growing student interest and more candidates appearing are the main drivers.

In 2026, fewer candidates than 2025 may slow the pace of increase. But unless the paper is much harder, closing ranks are unlikely to fall back to 2024 levels.

Cutoff Release Dates

The IISER IAT 2026 cutoff will come out with the Round 1 seat allotment list. This is expected in July 2026 on iiseradmission.in.

Each subsequent round will publish its own cutoff after allotment. The final round cutoff is expected by September 2026.

Admission Channels and Cutoffs

IISER 2026 has two main channels: IAT channel and JEE Advanced channel. Each has its own closing ranks at every campus.

Students who qualify JEE Advanced can apply through the JEE Advanced channel. These candidates are ranked separately and allotted seats from a reserved intake at each campus.

The JEE Advanced channel closing ranks differ from IAT channel closing ranks. Both are published on iiseradmission.in after each allotment round. IAT channel students do not compete with JEE Advanced channel students.

Eligibility Criteria

You need at least 60 marks per 100 aggregate in Class 12 for the General category. Reserved category students need at least 55 marks per 100.

This is the eligibility cutoff, not the admission cutoff. Your rank decides actual admission.

If you are registered, you automatically participate in all rounds unless you withdraw or miss the SAF payment. You do not need to apply separately for each round.

Freeze or Float Decision

Freeze your seat if you are happy with the campus allotted in Round 1. Choose Float if you want to try for a better campus in the next round.

Floating is safe because you cannot get a worse seat than your current allotment. If your first preference is already allotted in Round 1, freeze it right away.

IISER Admission 2026: Overview

The Indian Institute of Science Education and Research (IISER) admission process for 2026 is based on the IISER Aptitude Test (IAT). The official website for all admission-related information is iiseradmission.in.

Admission is offered to the BS-MS dual degree programme across seven IISER campuses. The campuses are Berhampur, Bhopal, Kolkata, Mohali, Pune, Thiruvananthapuram, and Tirupati.

Eligibility Criteria

Candidates must have passed Class 12 or an equivalent examination with Physics, Chemistry, and Mathematics or Biology. The qualifying examination must be from a recognised board.

For the general category, candidates must have secured at least 60% aggregate marks in their qualifying examination. For SC, ST, and PwD categories, the minimum aggregate is 55%.

Candidates appearing for the Class 12 examination in 2026 are also eligible to apply. They must provide their marks by the specified deadline.

Exam Pattern

The IISER Aptitude Test (IAT) is a computer-based test. The total duration of the exam is 180 minutes.

The question paper contains a total of 60 questions. Each subject section has 15 questions.

• Physics: 15 questions
• Chemistry: 15 questions
• Mathematics: 15 questions
• Biology: 15 questions

Each correct answer carries 4 marks. Each incorrect answer carries a negative marking of 1 mark. Unanswered questions do not carry any marks.

The total marks for the IAT are 240.

Application Fee

The application fee varies by category. The fee is non-refundable except in specific cases.

Payment can be made online through net banking, credit card, or debit card. The application fee is refundable only when a candidate withdraws their application. Check the official refund schedule on iiseradmission.in for details.

Important Dates

The official schedule for IISER Admission 2026 is released on the official website. Candidates must check iiseradmission.in for the exact dates.

These dates are tentative and subject to change. The final schedule will be published on the official website.

Seat Allotment Process

Seat allotment is done through a centralised counselling process. The allotment is based on the IAT score, category, and preference of campus.

Candidates must fill in their choice of campuses during the application process. The allotment is done in multiple rounds.

After each round, candidates must accept the allotted seat and pay the acceptance fee. Candidates who do not accept the seat are moved to the next round.

Score vs. Campus Cutoff

The required IAT score for admission varies by campus and category. The following are indicative scores for the general category.

A score of 100 or more marks targets IISER Berhampur or IISER Tirupati in later rounds for General category. A score of 160 or more makes you competitive for IISER Kolkata, Mohali, or Bhopal. A score of 180 or more targets IISER Pune.

For reserved categories, required scores are lower by roughly 20 to 50 marks depending on the campus. The exact cutoffs are released after each round of allotment.

IISER IAT Results 2026: Important Dates

The IISER IAT 2026 result has been declared on the official admission portal, iiseradmission.in. Candidates can log in using their application credentials to download their scorecard and check their rank details.

Will IISER Notify Candidates by Email?

IISER IAT Results 2026: Previous Year Statistics

The number of candidates appearing for the IAT has grown nearly eight times from 2022 to 2026, while available BS-MS seats have grown by only about 21% in the same period. In 2022, roughly 1 in 13 candidates could theoretically secure a seat. By 2026, that number has jumped to 1 in 79.

More students are choosing science research as a career path, and the IISERs' growing reputation — and the strong career outcomes of BS-MS graduates — are pulling in far larger pools each year.

How to Check IISER IAT Results 2026

Candidates can check the result on the official website iiseradmission.in. Log in with application credentials to view and download the scorecard.

How to Check IISER IAT 2026 Result

The IISER IAT 2026 result is available only through the candidate login on iiseradmission.in. There is no public roll-number-based result link.

Once the result goes live, follow these steps:

• Go to the official website iiseradmission.in.
• Click on the candidate login option.
• Enter your registered email ID and password.
• Download your result and rank card.

Use the "Forgot Password" option on the login page to reset it via your registered email. Do this now, before the result rush — the portal can get slow immediately after declaration, and you do not want to be locked out at that moment.

The portal typically slows down right after the result is declared due to high traffic. If you cannot access it, wait 20–30 minutes and try again. A mobile data connection sometimes works faster than Wi-Fi during peak traffic on the result day.

IISER IAT 2026 Result: Frequently Asked Questions

Can I check the IISER IAT 2026 result without logging in?

No. The result is only accessible through the candidate login on iiseradmission.in. There is no public result page where you can enter a roll number. Keep your registered email ID and password ready well before the result date.

What if I see an error in my rank card after downloading it?

If you spot any error in your name, category, date of birth, or other details on the rank card, report it to the IISER admissions team through the official portal immediately. Errors must be corrected before counselling registration — do not wait until the seat allotment stage, as it may be too late to fix them then.

IISER IAT Results 2026: Rank Card — Details Inside

Your IISER IAT 2026 rank card is the document you will use for counselling registration and seat allotment. Download it the moment the result is out, save a PDF copy, and keep a printout as backup — the portal may not always stay accessible during the counselling period.

Your rank card is a read-only PDF — it cannot be edited or regenerated with different details. If any detail is wrong, contact the admissions team at iiseradmission.in at the earliest. The rank card does not contain a college or branch allotment; that comes later through the counselling rounds.

IISER IAT Results 2026: Qualifying Marks

IISER IAT 2026 has no fixed qualifying marks. Any candidate with a positive score receives an All India Rank (AIR).

However, getting a rank does not guarantee admission, as seat allotment depends on your rank, category, and available seats.

With more than 1.86 lakh candidates competing for 2,343 seats, you need to be in roughly the top 1.3% to secure admission through the IAT route. Here is a practical guide to where different score ranges are likely to land in 2026, based on 2024 and 2025 trends:

IISER IAT 2026: Qualifying Marks FAQs

Is there a subject-wise minimum mark requirement in IISER IAT 2026?

No. IISER IAT does not prescribe any subject-wise minimum qualifying marks. Your total score across all four subjects determines your AIR. Even if you score zero in one subject, but your total net score is positive, you get an official rank — though your overall total will be lower.

What is a good score in IISER IAT 2026?

A score of 200 and above out of 240 is expected to secure a top 100 AIR in the General category. This score range is likely to get a seat in the first or second choice — IISER Pune or Kolkata.

IISER IAT Result 2026: Expected Cutoff

IISER does not publish a single cutoff mark. The opening and closing all-India rank (AIR) for each campus in each counselling round serves as the effective cutoff.

These ranks are published on iiseradmission.in after each seat allotment round. They vary by campus, subject, and category.

Based on 2025 trends, 175+ marks out of 240 is a strong score that can get you into IISER Pune or Kolkata. Scores of 150–174 are competitive for mid-tier IISERs.

With the 2026 applicant pool being 56% larger than 2025, a safe score for top IISERs may be closer to 185–190+ this year.

What After IISER IAT Results 2026?

Once the result is out, here is exactly what you need to do to convert your rank into a seat at an IISER campus.

1. Check and download your rank card

Log in at iiseradmission.in, note your AIR and category rank, and save a PDF copy. This is your starting document for everything that follows.

2. Register for counselling

Counselling registration opens on iiseradmission.in shortly after the result. You will upload documents and pay a counselling participation fee.

Missing the registration deadline means losing your chance at a seat — there is no extension.

3. Fill your choices carefully

During registration, fill in your preferred IISER campuses and subjects in order of preference. Seat allotment is strictly based on your rank and the order of choices you fill.

You cannot revise choices after the window closes, so think through every option before submitting.

4. Participate in seat allotment rounds

IISER runs 8–9 rounds of online seat allotment from around August to September 2026. After each round, log in to check your allotment.

You have two options:

• Accept and Float: Accept the current seat but stay in the pool — if a higher-preference seat opens in the next round, you get it automatically
• Accept and Freeze: Confirm the current seat and exit from further rounds

5. Pay the seat acceptance fee and complete document verification

Once you decide to freeze, pay the acceptance fee online and upload final documents. Physical reporting at your allotted IISER campus happens at the end of the process for final admission confirmation.

Keep these documents ready for IISER 2026 counselling:

• IAT 2026 rank card
• Class 10 and Class 12 mark sheets and certificates
• Category certificate (SC / ST / OBC-NCL / EWS / PwD), if applicable
• Valid photo ID (Aadhaar card or passport)
• Passport-size photographs (as specified in the counselling instructions)

IISER IAT 2026 Candidate Count and Seat Availability

More than 1.86 lakh candidates appeared for the IISER IAT 2026 on June 7, 2026. This is a jump of about 56% from 2025 (when ~1.19 lakh appeared) and makes 2026 the most competitive IAT year on record.

There are 2,343 BS-MS Dual Degree seats across seven IISERs — Pune, Kolkata, Mohali, Bhopal, Thiruvananthapuram, Tirupati, and Berhampur. Seats are distributed across all categories: General, OBC-NCL, EWS, SC, ST, and PwD.

Rank Card Details and Minimum Qualifying Score

Your IISER IAT 2026 rank card will show your name, roll number, subject-wise marks in Physics, Chemistry, Mathematics, and Biology (each out of 60), total score out of 240, All India Rank (AIR), and category rank. Download it immediately when the result is out and keep a PDF and printed copy.

There is no fixed minimum to qualify. Any candidate with at least one net positive mark after the +3/–1 scheme gets an official AIR. Practically, General category students need 130+ marks out of 240 to have a realistic chance at any IISER seat, and 175+ for top IISERs like Pune or Kolkata.

Marking Scheme

• Each correct answer gives +3 marks.
• Each wrong answer deducts 1 mark.
• Unattempted questions carry 0 marks.
• The maximum total score is 240 — 60 marks each for Physics, Chemistry, Mathematics, and Biology.
• Net scores can turn negative if you attempt many questions incorrectly.

Counselling Rounds and Seat Acceptance

IISER typically conducts 8–9 rounds of online seat allotment. The rounds run from around August through September. After each round, you choose to "Accept and Float" (stay in the pool for a better seat) or "Accept and Freeze" (confirm your current allotment). The final round closes admissions for the cycle.

If you receive a seat allotment but do not accept it within the given window, your allotment is cancelled and the seat goes back into the pool for the next round. Accept your allotment — even if it is not your first preference — and choose "Accept and Float" to keep your options open for a higher-preference campus in subsequent rounds.

Admission Routes Without IAT

Yes. IISER also admits students through JEE Advanced rank and the INSPIRE-SHE scholarship channel. If you have a strong JEE Advanced rank, you may not need to appear for the IAT at all. All three routes lead to the same BS-MS Dual Degree programme. Check the official IISER 2026 admissions brochure on iiseradmission.in for eligibility details for each channel.

Difference Between IISER Campuses

All seven IISERs offer the same five-year BS-MS Dual Degree programme with a research focus. The difference is reputation, location, and closing rank. IISER Pune and Kolkata are the oldest and most sought-after, so their closing ranks are the tightest. IISER Berhampur and Tirupati are newer with more relaxed closing ranks — making them more accessible to candidates in the 900–1,500 AIR range. All IISERs are autonomous institutions of national importance under the Ministry of Education.

Score Interpretation

In the IISER Aptitude Test (IAT), a score of 75 marks out of 240 is generally a lower score that makes admission unlikely for General, EWS, and OBC candidates. However, for SC and ST category candidates, it is considered a decent qualifying score that can secure a seat at newer campuses like IISER Tirupati or Berhampur.

In the IAT, scoring 70 marks out of 240 generally results in an All India General Rank (AIR) above 8,500. While this score makes a seat unlikely for General category candidates, it can yield a competitive rank for SC/ST candidates, making them eligible for campuses like IISER Tirupati or Berhampur.
