ConclusionWay forward, balanced suggestion, or tie back to constitutional values. Avoid generic conclusions.
Diagrams & TablesA relevant diagram/table in GS-1 Geography, GS-3 Economy/S&T can earn extra marks. Use them judiciously.
Answer Booklet ManagementLeave 5–6 pages blank before each answer. Examiner should be able to locate your answer quickly. Number ALL pages.
