NHPC JE 2021 official syllabus and examination pattern – Mechanicaltalks

NHPC JE official syllabus for mechanical Engineering

Students are eagerly waiting for the NHPC JE examination. It is likely to be held in mid or end of November. The commission has released the official syllabus for different different branches.
 

The examination pattern are like this –

General Intelligence and reasoning = 30 marks
General awareness = 30 marks
Branch paper / domain = 140 marks.
Total marks = 200 
Time = 180 minutes ( 3 hours ).

The detailed syllabus are discussed below –

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.
