Hi Sanjay.

I hope you know how seats are allotted in case of preparatory students. Seats to students from the preparatory list are only alloted when seats are left after all the rounds of counseling have been finished. They are usually allotted to students whose rank is below 100. Do, you don't have any chance whatsoever to get into IITs. I would suggest you to take a year drop and prepare for JEE Advanced again.

Al the best
