Dear aspirant !

Hope you are doing great ! Firstly be clear with that jee mains marks and rank doesn't matter for any iit ,you just need to be in top 2.5 lakh to sit for jee advanced and on the basis of jee advanced you can get the admission in IITs .

JEE Advance exam pattern keep change every year. So the exact prediction would be tough But try to score more than 60% as a genneral category in JEE Advance entrance exam to get admission in IIT Bombay.

Hope it helps you !

Thank you
