Political science is the study of politics, political institutions, government affairs and public administration and an expert in this field is called political analyst.

Since you are doing B.Tech and now you want to change your field with political science , you can opt for programmes in humanities which are available at all levels - Bachelor’s, Master’s and Doctorate. In these programmes, you can study peace and conflict issues, gender studies, human rights policy making, and political sociology apart from national politics, comparative government, and international politics.
