Hello Usha,

The path is quite difficult but not impossible. For this you will have to take science in class 11th. You should prepare for NEET or JEE main well, and get into colleges such as IIST from where ISRO directly recruits students for the post of Junior Scientist. You also have the option to give KVPY exam. Clearing this will admit you to IIST or colleges such as IISC Bangalore. Colleges like this give you preference when you apply in ISRO. In case you are not able to make to these colleges, go for some other good college and prepare for ICRB exam. Take core branches such as CSE, MECHANICAL, EEE, or ECE. you can also get a chance by clearing GATE.

Hope this Helps
