Dual

Hi Keerthi Rajan,
Kindly mention the paper/exam name which you wish to know about for better understanding.

I guess, you are a bit confused in understanding the eligibility criteria with 10+2. It means, your class 12th or PUC grade, not your class 10th. So, better start focusing on your subject to get your dream college.

There is no such best specialization. All the specializations go well with the dual degrees.

All the IIT's
IISER's
NISER, Bhubaneswar
BITS, Pilani
IISc, Bangalore.

According to me, chemistry has more scope:
You can become a scientist in a reputed lab if you know chemistry, wherein, by doing maths, you can still become a researcher but not as good as a scientist.
You can do research in the medical field, chemical field, human body, forensic science and many other. You can make your career in the teaching line as well. Now, the choice is all yours.

Yes, one can opt for Dual specialisation in this college.

Tezpur University has a dedicated Training and Placement Cell for handling placements in the campuses. Many reputed companies do visit the campus for recruitment but getting placed is solely on one's capability. You can check the Placement Scenario here from the 2017 National Institute Ranking Framework Data NIRF 2017 DATA, Tezpur University.

You need to contact the Controller of Examinations, TU during office timings on non-holidays. The office is always available for such issues, not others.

You have already completed your MBA, so it is not required to do pursue dual PG.
