What the IISER Round 4 Allotment Letter Shows
When you log in to check your allotment, the offer letter on your dashboard will display important details such as your name, application number, IAT rank, category, the IISER campus and programme you have been allotted, and the deadline by which you must respond. It is important to carefully verify all the information. If you find any mistakes or discrepancies, you should report them immediately using the official grievance process available on the admission portal.
What Happens After Round 4?
If you do not get a seat in Round 4 or choose to float your seat (meaning you want to try for a better option in the next round), you will be considered in Round 5 counselling. Round 5 is scheduled from August 24 to August 26, 2026. Usually, seats become available in later rounds because candidates with higher ranks may upgrade to preferred campuses, freeing up seats for others.
If you decide not to continue with the counselling process, you can withdraw your application through the portal. Keep in mind that withdrawal and refund rules depend on the institute’s policies.
