I completed this paper and received AIR-49 in writing, but was unable to pass the interview.
- These papers from previous years are very important. You should solve them and analyze the topics that you didn’t cover in preparation for other exams such as RADAR or satellite communications. Make sure to take proper notes.
- ISRO paper is a pure theory-oriented paper. However, you can use numerical to prepare it.
- Some topics are more focused on communication system. Work more on these topics.
This paper is very time-consuming in choosing a reference book. It is very easy to crack.
I made a list of topics, searched the web topic-wise, took notes, and then revised.
