Hello Bindeshwar,

The SCRA exam is one of the most technical exam in india and maybe tougher than JEE Advanced based on no. of seats and the examination pattern though one needs to have a General awareness around him and about the world but there isn't a specific need to have a study of General Knowledge as Required in exams like SSC ,its basic Requirement can be fulfilled and understood by giving mock tests and solving the previous year's question paper and one can easily understand the radius of topic coverage and amount of study required for clearing the exam based on previous years papers and mock tests.

I hope this solves the query

Best Wishes
