UPSC IES: Indian Engineering Services Exam Electronics and Telecommunications Engineering (ENTC)  Syllabus

Dear MockBankers

Following is the syllabus for the UPSC IES Electronics and Telecommunications Engineering (ENTC) examination.

General Ability Test Syllabus

Part A : General English : The question paper in General English will be designed to test the candidate’s understanding of English and workman like use of words.

Part B : General Studies : The paper in General Studies will include knowledge of current events and of such matters of everyday observation and experience in their scientific aspects as may be expected of an educated person. The paper will also include questions on History of India and Geography of a nature which candidates should be able to answer without special study.
