On Question asked by student community
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 !
Hello,
If you have selected OBC-NCL category and uploaded a Central OBC-NCL certificate , then there is no issue .
IISER accepts Central OBC-NCL certificate , as long as it is valid and issued by a competent authority. Just make sure the certificate is:
Issued within one year from the application date.
Clearly mentions OBC-NCL and your caste is in the central list .
If these points are okay, then your form is fine.
Hope it helps !
Hello aspirant,
Applicants must take either the JEE Main or JEE Advanced exam in order to be considered for admission to the best engineering institutes in India. JEE Advanced and Main are administered by separate bodies. Because the JEE Advanced exam is more difficult than the JEE Main exam, candidates who are prepared for it have an advantage.
