Yes Koushika,

The exam pattern has been changed to objective type. The link of the prospectus is as follow, https://jnu.ac.in/admission/e-prospectus-2019-20.pdf

The course of the exam is described as

International Relations and Area Studies – IRAM

Five disciplines are covered in the test – Sociology, Political Science, International

Relations, History. There is sufficient choice in questions for applicants from each

discipline to be able to attempt the required number of questions. The BA syllabi of

these disciplines generally found in most Indian universities are kept in mind while

setting questions. The emphasis will be on Area Studies in International Relations. ( page 142)

Hope it will help you.
