It includes a common General Studies paper of 100 marks and a stream-specific paper carrying 300 marks. A penalty equivalent to one-third of the marks assigned to a question applies for an incorrect answer.

Stage II is the Main Examination carrying 600 marks. It consists of three conventional descriptive papers of 200 marks each, with three hours allotted to each paper. The Main Examination is specified as being conducted in English medium. Candidates who qualify through the written stages proceed to the Personality Test, which carries 200 marks.

The final merit position is determined from performance across the prescribed examination stages and Personality Test. Since the supplied notification summary does not provide a detailed subject-wise topic list or exact question counts for every paper, those fields have not been assumed here.
