Good evening

Only you can decide which subject fascinates and easiest for you between political science and public administration. But, I can surely give you an overall idea about what kind of study do both of these subjects offer.

Political science and international relations is a vast subject. For its preparation you will need to study many books and magazines. Yojana and editorials will also immensely help you for the preparation of this subject. You will also need to listen to various political debates on Rajya Sabha TV, BBC, etc, especially for the preparation of IR.

Whereas, public administration will require a limited study. The resources for studying this subject are comparatively few. But, since this subject has a shorter syllabus, it will require a simpler study plan.
