How can I become a scientist at ISRO or at any space research organisation?.( i am preparing for jee)..

@ shivam 
, once u got a rank in jee advanced , try to get into the iisc bangalore , and after that go for research organisation , and after that u will become a scientist in postgarduate level . 
after clearing jee u can choose any one of the following institutions 
1- NISER 
2- IISER 
3- IISC , etc , are the top institute for research . 

ALL THE BEST ..
