Dear sir ,what is the date to fill form of iiit hydreabad on the basis of jee main?

Hello Candidate,
After conducting Jee Main April session NTA will officially declare the qualifying list and the institute wise cut off list. If you secure the required percentile and rank, you'll be eligible for the counseling process, and then after that you need to fill up the final admission form.
I hope this answer helps
Comment if you have any query
all the best :)
