Hello student,

In order to becoeme a cosmological scientist you need to go through these steps:

• complete your class 10 then +2 with science stream (PCM)
• get admission in universities which offer B.Tech, M.Tech, MS, PhD programs in Avionics & Aerospace engineering .

In india the top most institute is IIST  and to take admission to the undergraduate programmes offered by IIST  you have to appear for the IIST Admission Test (ISAT) conducted every year .

Hope it helps. 

Thank you  :)
