Hello Jericho Jonah ,

You can choose between MSc Astrophysics and MSc Physics....

After Bsc physics you can join as Technical Assistant, ISRO allow you option of part-time/correspondence study, after completing Msc you can get promoted to Scientist......

As a Bsc Graduate in Physics one can apply for the post of STA-B (Senior Technical Assistant- B) in DRDO. It is a Group-B, non-gazetted, non-ministerial post.....

Hope this help

Thank you !
