Geography

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

Reasoning, Geography and GK is not a compulsory requirement along with PCM to become a pilot. Aviation subjects for pilots are as under:
1. Air Navigation
2. Aviation Meteorology
3. Air Regulations
4. Aviation Technical
5. Aircraft Specific
6. Radio Telephony
They will be taught to you in the flying school and you will have to get through the DGCA exams for all of them to get the CPL issued.

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.

If you don't live in Bihar, then I think yes. I am providing you the following link so that you can check the locations of the study centres:

Hello Ramesan,
It's an interesting degree that you have. Normally speaking as one of the subjects is geography, I see no reason why any other university can deny you permission for doing PG in geography. But then proof of pudding is in eating. Best wishes
