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:
- Candidate can FREEZE the seat (they will not participate in further rounds of counselling),
- 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.

It is quite difficult for the GEN / OBC category to get admission to IISER with 50 marks. Even the reserved category students have less chance in the later counelling round for admission. To secure admission, students must score above 150 marks.
