(Syllabus) SSC : Junior Engineer (CPWD) Examination
Syllabus : SSC : Junior Engineer (CPWD) Examination
The standard of the questions in Engineering subjects will be approximately on
the level of Diploma in Engineering (Civil/ Electrical/ Mechanical) from a
recognized Institute, Board or University and recognized by All India Board of
Technical Education. All the questions will be set in SI units.
-
General Awareness:
Questions will be aimed at testing the candidate's general awareness of the environment around him 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 Sport, History, Culture, Geography, Economic Scene, General Polity, Indian Constitution and Scientific Research, etc. These questions will be such that they do not require a special study of any discipline. -
