Dear candidate!

No there is no such change in the criteria or admission process announced till now

To be eligible for JEE Mains a candidate must have qualified class 12th with PCM and secured a minimum of 50% aggregate as well as seperately in PCM in the qualifying examination.

For NITs, IITs, IIITs, and GFTIs, you must have secured 75% aggregate or be in top 20 percentile in the respective boards.
This is the official criteria announced as per the conducting bodies

Hope this was helpful :)

Wishing you luck!
