Hey Santhosh! IIST Admission is organized by Indian Institute of Space Science and Technology. Admission is offered into UG and PG courses in various fields. No entrance exam is organized by the Institute and the admission is provided on the basis of scores of national level exams – JEE Main, JEE Advance, GATE, JEST, UGC NET etc. 

Hello Rajan Kumar. 

Sorry but I could not understand your question properly. But what I understood from your question is that you are asking whether you can get a seat in IIST due to you JEE Mains marks and rank. 

Sorry but you cannor get a seat in IIST on your JEE Mains basis. But you can get admission on the basis of your JEE Advance result. 

Hope it helps you.

Hello dear student! 

Greetings! 

IIST B.Tech admission 2019 was on the basis of JEE Advanced 2019 exam. So class 12th marks doesn't play a big role , you just need to get at least  75 % in class 12th to be eligible .

Candidates can refer to the cutoff of IIST B.Tech admission for past five years as given below in the link :-
