Candidates should study the policy cycle, including agenda-setting, formulation, implementation, and evaluation. Familiarity with recent policy changes and their impacts on society is vital. Engaging with case studies and analyses helps develop analytical and practical understanding. Additionally, grasping the socio-economic and political implications of policies provides a holistic view essential for both exams and civil service responsibilities.
