Tips to prepare ISRO Scientist / Engineer (SC) Exam:

How to prepare ISRO Scientist / Engineer (SC) Exam:

  • Firstly list out all subjects and start preparation accordingly previous.
  • Instead of memorizing it’s better to focus on research and understanding topics while preparing for the topics. It will help you to crack the interview after the written exam.
  • To cover the topics for ISRO exam you can depend on GATE syllabus or undergraduate syllabus because more than 90 percent of ISRO questions will be asked from GATE.
  • One must practice previous year questions of ISRO once the syllabus is covered as 20 to 30 percent of questions would be repeated from previous year.
  • ISRO questions may be easy type but requires understanding of fundamentals as most of the questions of ISRO exam depends on facts, formulas and methods/techniques so practice the questions from GATE, DRDO, other exams previous year questions.
