Hello Debkanta, The syllabus for this exam is of the level if graduation. Hence you should be thorough in your knowledge about the subject that is taught at graduation level. In addition to be sure, try to take online mock test. That's all.

No, you cannot pursue any honors degree without studying it in your higher secondary.

Hello Vivek, Surely you can pursue Ph.D. in a related topic from IIT Patna. You only need to follow procedure set by this IIT for admission as Ph.D. student.

JNU is the university, ranked at no. 2 in university ranking list (2018) by NIRF. And at undergraduate level only there are linguistic papers ( like French, german, spanish, japnese, chinese, russian, korean etc. And many others). There is no geography and all other social Science and humanities and Science papers. Thanks.
