IISER Mohali Cutoff 2025: Previous Years Cut off Trends for All Courses

Hello,

If you have uploaded the old EWS certificate (2024–2025) instead of the new one (2025–2026), there is a chance that it may not be accepted, as the IISER notification clearly asks for the valid and updated EWS certificate for the year 2025–2026.

Right now, if the correction window is closed, you won’t be able to change it. But don’t worry too much. Once the results are out and before the counselling starts (before 16 June), there is usually a document verification process. You may get a chance to upload the correct and updated certificate during that time.

Just make sure you get the 2025–2026 EWS certificate ready as soon as possible, so if they allow updates before counselling, you can upload the correct one.

Hope it helps !
