Download SSC JE Mechanical Engineering 2020 Syllabus

SSC JE Exam has 2 papers- Paper I and Paper II as a part of the Examination process. SSC JE Exam was scheduled to commence from March 30th 2020 onwards but the commission decided to postpone the exam due to the Coronavirus pandemic.

Any new information or change will be cleared in SSC JE 2020 Notification.

The Detailed Syllabus for SSC JE Mechanical 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.
