Hello student ,

According to previous year Gate 2016 & 2017 cutoff, you may gate call for Aerospace Engineering Written/interview at IIT BOMBAY at 540 Gate Score which is Approximately 51 marks.

But 540 Gate Score is just cutoff its doesn't guarantee selection, in my opinion you should have Above 65 marks at least or nearly 700 gate score to hold a decent chance of selection as good weightage is given to gate score with written/interview performance .

Hope it helps !
