Good Luck!!

To get admission in IITs, you will have to clear Jee advanced exam but the paper pattern of jee advanced keeps on changing every year so it is quite difficult to provide any marks or rank range but to get admission in top IITs like IIT Bombay, you will have to get more than 60%.

Hope this helps!!!
