SSC JE Syllabus for Electrical Engineering

SSC JE Syllabus for Electrical Engineering - Staff Selection Commission invites the application every year for the post of Junior Engineer - Group B (non-Gazetted) in the central government departments. SSC JE exams have very popular in engineering graduates and diploma holders students because of very good position with attractive salary packages.

SSC JE Examination 2018 application almost done and now students have started their preparation, they are always worried about examination pattern, syllabus and how many no's of questions asked in each section. In this articles, we discuss in details SSC Junior Examination syllabus for Electrical Engineering.

How do I prepare for SSC Junior Engineer

SSC JE Examination Pattern

SSC conduct online exams for the selection of Juinor Engineer in central government department like-  CPWD, MES, Farraka Barrage, Director General Border Roads Organisation and National Technical Research Organisation.

SSC JE Electrical Engineering Exam will comprise of 2 papers. Paper I has a computer-based test of multiple choice question from General Awareness and Intelligence, Reasoning and General Engineering. Paper II has an offline written test in which only those candidates appear who have qualified the paper I.

		b.General Intelligence Reasoning	50
		c.  Mainstreams (Civil/Electrical/Mechanical)	100
Paper - II	Written Exam	Mainstreams (Civil/Electrical/Mechanical)	300	02 hours

SSC JE Examination Syllabus for Electrical Engineering

Paper-I

Part-A  (General Intelligence, Awareness & Reasoning)

General Intelligence & Reasoning: The Syllabus for General Intelligence would include questions of both verbal and non-verbal type. The test may include questions on analogies, similarities, differences, space visualization, problem solving, analysis, judgement, decision making, visual memory, discrimination, observation, relationship concepts, arithmetical reasoning, verbal and figure classification, arithmetical number series etc. The test will also include questions designed to test the candidate‟s abilities to deal with abstract ideas and symbols and their relationships, arithmetical computations and other analytical functions.

General Awareness: Questions will be aimed at testing the candidate‟s general awareness of the environment around him/her and its application to society. Questions will also be designed to test knowledge of current events and of such matters of everyday observations and experience in their scientific aspect as may be expected of any educated person. The test will also include questions relating to India and its neighbouring countries especially pertaining to History, Culture, Geography, Economic Scene, General Polity and Scientific Research, etc. These questions will be such that they do not require a special study of any discipline.
