IISER Entrance Exam

There is no fixed number of entering preference for the IISER Entrance Exam counselling process. There are seven IISER institutes offering 11 programmes. Candidates have to select at least one IISER. Higher the number of preferences, better will be their chance of seat allotment.

Once the IISER Entrance Exam counselling seat allotment result is declared, candidates have the following options.

• FREEZE: By selecting this option, candidates confirm the acceptance of the offer, and that they will not participate in the next rounds of IISER Entrance Exam counselling. 
• FLOAT: Selection of this option means 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.

Seat Acceptance Fee or SAF is the fee to be paid to accept the allotted seat at a particular round of IISER counselling process. Unless the SAF is paid, candidates will not be considered for admission. 

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.
