The Civil Services Examination (CSE) is considered to be the mother of all written examinations. It is a curriculum heavy examination especially at the Main exam stage. A candidate, therefore, has to begin preparation for the Main Exam and then for the Prelim. This is so because, if one starts his preparation for the Main exam after the having written the Prelim exam, he will have just four months (June to October) to prepare the Optional subject, Essay and General Studies, which is almost impossible to achieve. The optional subject is of post graduation level and usually it will be totally a new subject.
