IAT Exam 2025 Cut Off: Check IISER, IISc Banglore & IIT Madras Merit List, Cut Off/ Closing Rank Here

IISER Marks vs Rank is generally the data interpretation of the candidates who had appeared in the IAT examination. Here, candidates will be able to know the expected AIR rank/ category rank that they will achieve based on the marks scored by them in the IISER examination. 

IAT candidates' ranks are based on their combined scores from the four sections (Physics, Chemistry, Mathematics and Biology). The exam comprises 60 questions with a total score of 240 marks. 

The cutoff rank for IISER will be released online. Meanwhile, students can check the previous year cutoff of IISER to know what rank is required for admission.

In the event that there is fewer number of seats available under a particular category in an academic programme than the number of
candidates with the same category-wise rank seeking admission to the B.S. (Medical Sciences and Engineering) program, then all those candidates will be offered seats by creating requisite number of supernumerary seats.

Following the previous years' trends, the exam officials release the round-wise IISER institute-wise closing ranks. IAT cutoff marks refer to the minimum marks test takers need to score to get admission in the programmes offered by the participating institutes. 

The following rules for reallocation of seats will be applicable in every round of seat allocation:

Unfilled OPEN PwD category seats for an academic program will be reallocated and treated as OPEN category seats for allocation.
Unfilled GEN EWS PwD category seats for an academic program will be reallocated and treated as GEN-EWS category seats for allocation.
Unfilled OBC NCL PwD category seats for an academic program will be reallocated and treated as OBC-NCL category seats for allocation.
Unfilled SC PwD category seats for an academic programme will be reallocated and treated as SC category seats for allocation.
Unfilled ST PwD category seats for an academic programme will be reallocated and treated as ST category seats for allocation.

During the IISER Entrance Exam counselling process, seats are allotted based on the following factors.

• Seats available across IISER institutes in the current round of counselling
• IAT Rank obtained by candidates
• IISER preference given by the candidate
• Candidate category.

Candidates are advised to fill as many colleges as they wish to, to increase their chances of seat allotment. 

The portal for document upload and freezing of IISER preferences for IISER 2026 Admissions is expected to begin in the month of July 2026, tentatively. After accepting the offer and paying the seat acceptance fee, the candidate can exercise two options:

1. Candidate can FREEZE the seat (they will not participate in further rounds of counselling),
2. Candidate can FLOAT (they will participate in further rounds of counselling to get their higher preferences). The FLOAT option is activated by default for those who pay the seat acceptance fee. A student who has chosen to FLOAT will again be considered for seat allocation in the next round. If they are eligible to secure a seat in an IISER that is higher in their preference list than the currently accepted one, they will be offered that seat.
