I got 91.51 percentile in 2021 ,can i get seat in good iit colleges and rank around 60000

Hi, you have not mentioned which category you belong to, assuming that you belong to general category with 60000 rank it is difficult to get seat in IITs. You should qualify in JEE Mains to get seat in IITs. By luck if you get seat also you may not get seat in top branches. You can boost your rank by using rank booster, below I have provided you with the link.
