Freeze or Float Willingness Options

After viewing the allotment, candidates must choose one of two willingness options on the portal. This choice decides participation in any further round.

Freeze: Accept the current seat and exit the counselling process. No upgrade will be considered in later rounds.
Float: Retain the current seat but stay in the pool for a better preference in later rounds.

Both options require the SAF payment by August 20, 2026. Missing the deadline leads to automatic cancellation of the allotted seat.

Why This Round Matters

Round 4 is one of the last chances to secure a BS-MS seat across the seven IISERs. Vacancies at this stage are limited and usually shift among top preferences. A quick decision on freeze or float can protect your final allotment.
