Hello.

While preparing for Political science it is important that you focus on basic concept, theory and ideologies and have to focus on main ideas such as Social contract,rights,liberty,etc. You have to gain knowledge on independent India's history and also have to read about the contemporary events and political scenario of India. There are several books available specifically for entrance exams that can give you a brief idea about the pattern and type of questions asked. You can also go for some Delhi University books.
