Hello Lokesh

The entrance exam of JNU for the academic year 2019-20 will be held in May and format of the exam will be Multiple Choice Questions through a Computer Based Test.
Since there is a change in the examination format this year, we will have to wait for the prospectus to be released by the University for other details and it is expected to be announced shortly by the University. Refer to the link below- https://jnu.ac.in/sites/default/files/admission/Revised%20Admissions%20Notice_Dec%2012%2C%202018.pdf

Good Luck!
