Hi,
B.Tech or BE from India is preferred as you can apply to government jobs. If you have no plans of doing it, you may pursue it from Australia or any other country of your choice. Another point to keep in mind is the cost. The cost at IITs, NITs and IIITs is always cheaper than the private universities and placements are better too.

Hi,
It's difficult to tell the exam centres as it depends on the region and number of students taking the exam.

Both streams have good placements in India as well as Abroad.
Nowadays, India has a confirmed 100% FDI in both the fields. So you have good scope to develop your career in these fields.
In India, ISRO, DRDO and Indian Air Force, especially many Indian companies also invite aeronautical and aerospace engineers.
As for abroad, NASA hires engineers having the specialised skill set in these fields.

Hi. Both of the courses have their own pros and cons. I'll state some aspects for comparison between the two:-
1. Degree: MBA: awarded by University; PGDM: given by the individual college.
2. Placements: Almost same for both.
3. Curriculum: MBA: university decides; PGDM: college decides.
4. Exposure: Similar for both.
5. Cost: MBA: Generally is less costly; PGDM: Generally a bit costly.
6. Pedagogy: MBA: Usually more theoretical; PGDM: Usually more practical.
I hope it helps!
