Sir, I am a ST student looking forward to get a seat for Aerospace engineering branch in the respective IITs or IIST. Presently I am at 11^th. How much do you think should I have to score in JEE(adv) to get a seat for?

Please sir it would be very kind of you!

dear techi 
as jee adv changes the total no of marks every year , so, we cannot predict the actual mark . 
but i can say you need to score around 2500-2700 rank to get aerospace in the iit , 
and acc to the last year data , u need to score 250+ marks . 
HOPE IT CLEARS 
REGARDS
