Sorry Naveen ,But your rank will not be able to fetch you a seat in any of the IITs as per previous year trends.The closing OBC category ranks are generally last upto 6000.So don't expect much from JEE ADVANCED rank.You should focus more on the colleges accepting JEE MAIN ranks.

Use the college predictor to have an idea.

All the best for your future. 

Hi there,
Hope you are doing well.
I am really sorry to say but with 7500 rank in JEE Advanced OBC Category, you can't get a seat in any of IITs.
The final closing rank to get admission is 3800 for admission in IIT BHU B.Tech. + M.Tech. - Pharmaceutical Engineering & Technology 

Hope it would help
