Hello Aspirant,

Since you have not mentioned your category so considering it as General if not then please correct me.

As we go through the latest cut-off of 2020 then it shows that the closing rank for General/Open category was 2070 for Aerospace Engineering branch in IIT Bombay. See it is quite difficult to tell you about exact marks to score because for JEE-Advance no maximum marks are fixed but yes with regards to JEE-Advance 2021 if you secure your AIR in JEE-Advance under top 2050 then there are good chances for you to get Aerospace Engineering branch in IIT Bombay.

You can check out the latest cut-offs from the link given below :-
