The standard of the questions in Engineering subjects will be approximately of the level of Diploma in Engineering (Civil, Electrical, Mechanical etc) 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.
  • The details of the syllabus are given below.

PAPER I – Part i (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.

PAPER II – Part 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 neighbouring countries especially pertaining to History, Culture, Geography, Economic Scene, General Polity, and Scientific Research, etc. Thesequestions will be such that they do not require a special study of any discipline.
