Hi Paras,

IIST, one of the most prestigious institute for space technology takes admission on the basis of JEE. It is highly competitive exam so u must prepare for it well. The cutoff varies every year so have a visit on its official site.

First fill the JEE form. A time period is announced by IIST to fill their form too. Fill their form. If you cross the cutoff, you will be admitted. For cutoff & application date, visit IIST website https://www.iist.ac.in/admission...

By qualifying JEE mains and JEE advance.

One must register himself/herself for IIST, and the selection will be based on JEE advance rank.

All the best :)
