Please read the indicative syllabus for NTPC Exams for various disciplines. National Thermal Power Corporation conducts various recruitment exams and this syllabus will help you base your studies on selective topics.

This syllabus will let you know about the topics to be covered for Engineering, Management and Finance related jobs at NTPC. If you go through previous papers for NTPC you will find that the questions broadly revolve around the prescribed syllabus. Its better that you stick to these when you start preparing and then focus on other material for extra details.

We wish you luck for your exams.
