Hey! 72 marks in jee advanced are somewhat less and getting into iist is a bit difficult. With 72 marks I don't think you will be able to get into iist since there are only very limited number of seats and given that it's one of the best space institutes in india. Hence getting there would be somewhat difficult. Work hard for this seat. Hope this answer helps.

Hello Ramakrishna

IIST, Thiruvananthapuram is a very prestigious university. It is impossible to deduce whether you will get admission next year i.e 2020 with 72 marks. I would rather suggest that you focus on securing good marks in JEE Main and JEE Advanced by hard work and you will definitely get admission in IIST. Good Luck!

Thank You.
