The Detailed Syllabus for SSC JE Electrical Engineering is given below:

Paper 1: 

(i) General Intelligence & Reasoning: The Syllabus for General Intelligence would include
questions of both verbal and non-verbal types. The test may include questions on analogies,
similarities, differences, space visualization, problem-solving, analysis, judgment, 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.
(ii) 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 neighboring 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.
