Hello,

It is difficult to predict the marks with which you may get seat in B.tech Aerospace Engineering in an IIT. The cut off will be different for each IIT. For instance the cut off rank for admission in to IIT, Bombay in B.tech Aerospace Engineering for SC category in 2020 JoSAA round 6 counselling was 591, for IIT Kanpur it was 1077, for IIT Kharagpur it was 1075 and for IIT Madras it was 1068. Considering the previous year cut off you need to score minimum 50-55% of total score in JEE Advanced to secure a rank below 1000. The total marks for JEE Advanced changes every year. Cut off tends to change every year depending on factors like number of candidates appeared, difficulty level of exam and number of seats available etc.
