Dear Soumyadip,

As if we talk about cracking the ssc je exam so the syllabus consists of the three parts General Intelligence and reasoning,General Awareness,General Engineering. I will let you know about each content seperately.

So first one is General intelligence:-

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.

Second one is General Awareness:-

Questions will 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.

Third one is General Engineering:-
