Hello Rakesh,

Indian Institute of space science and technology (IIST) Thiruvananthapuram is a renowned college for providing course in space research and related fields. It works in collaboration with ISRO And this gives a chance to the students to get absorbed in ISRO. Admission registration for 2019 had already been started and the registration will close on 17 june19. 

IIST takes it admission for BTech on the basis of JEE advanced ranks and the merit list is prepared on the same . For participating in admission process one need to score 75% marks in 12th standard or its equivalent exams for general category as for sc/St,obc,pwd it is 65%.

Minimum marks to be achieved in JEE advanced category wise is as follows:

General- At least 20% marks in aggregate and at least 5% marks in each of the three subjects (Physics, Chemistry and Mathematics).

OBC- Non Creamy Layer (OBC-NCL) Candidates: At least 18% marks in aggregate and at least 4.5% marks in each of the three subjects (Physics, Chemistry and Mathematics).

SC/ST &Pwd- At least 10% marks in aggregate and at least 2.5% marks in each of the three subjects (Physics, Chemistry and Mathematics).

For registration students has to go on IIST official website only.

So I think you will not be able to make it to IIST with JEE main,as you also need to appear for JEE advanced. And fullfill the criteria. IIST does not hold any separate exams for its admission.

Hope this helps. Further if any queries feel free to ask.

All the best!!!

Regards.
