2. Selection of the right BTech Degree

Electronics and Electrical Engineering: If you're interested in working on satellite systems, instrumentation, or communication systems, having a background in electronics and electrical engineering will help. Subjects like digital electronics, microprocessors, and circuits are crucial for hardware-related jobs in ISRO.

Aerospace Engineering: For those particularly keen on spacecraft, propulsion systems, or satellite technology, taking subjects related to aerospace engineering (if available) in school or pursuing it in higher studies is a natural choice. 

Which Exam to Take to Become a Scientist in ISRO?

Once you have completed your Class 12, the next step is to pursue a degree in engineering or technology. After that, you’ll need to crack competitive exams to become a scientist at ISRO. There are two main exams you need to be aware of:

1. JEE (Joint Entrance Examination):

The JEE is a nationwide entrance exam required to gain admission to prestigious engineering colleges in India, including the Indian Institutes of Technology (IITs) and National Institutes of Technology (NITs). A B.Tech degree from these institutions is a key qualification to apply for scientist roles at ISRO.

• JEE Exam Eligibility: After Class 12 with Physics, Chemistry, and Mathematics.
• Examination: JEE consists of two parts, JEE Mains and JEE Advanced. You will need to clear JEE Mains first and then qualify for JEE Advanced for admission to top engineering colleges.
• Courses to Pursue: 
       - B.Tech in Aerospace Engineering
       - B.Tech in Electronics and Communication Engineering
       - B.Tech in Electrical Engineering
       - B.Tech in Mechanical Engineering

2. ISRO Centralized Recruitment Board (ICRB) Exam:
After completing your undergraduate degree, you can apply for the ICRB exam. This is a specific exam held by ISRO to hire engineers and scientists. ISRO conducts recruitment for various scientific positions through this exam, usually once a year.  

• Eligibility: A B.Tech or BE degree in the relevant field (Aerospace, Electronics, Mechanical, etc.) with a minimum of 65% marks (for general category students).
• Examination: The ISRO exam typically consists of two parts: a written test (usually technical) and an interview.
• Fields: Depending on your area of specialization, you can apply for positions in areas like Space Science, Satellite Engineering, Propulsion Systems, and more.

How to Become a Scientist in ISRO through MSc or PhD

While a B.Tech or BE degree is the most common route for joining ISRO as a scientist, there are alternative paths for students who have completed their MSc or PhD. These paths are usually for candidates interested in research roles, scientific exploration, or specialized projects at ISRO. Here’s how to proceed:

   If you have a background in Science (B.Sc. or MSc) with a specialization in physics, mathematics, or electronics, you can apply to ISRO’s scientist positions after completing your MSc.
