Hello student, 

Indian Institute of Space and Technology (IIST) offers both UG and PG admissions. 

To get into IIST one need to apply for it through online form that is generally released in first week of June (generally after Jee Advanced examination). 

While applying you can select your branch preferences (Aerospace, ECE etc.  for B. Tech). 

Remember one thing, one need to be eligible under their criteria to get admissions. 

1. One need to be an Indian citizen. 

2. One's aggregate marks in 12th boards in five subjects (Physics, Chemistry and Maths compulsory) must be greater than 75 percent. (65% for SC/ST). 

3. One need to appear in Jee Advanced and secure at least 20% of total score, including 5% in each subject. (18% and 10% for OBC and SC/ST respectively). 

After fulfilling the above criteria and registering,  you could get a chance for IIST. 

Hope this will help. 

All the best for future.
