Dual

Hello,
Anxiety about packages at the time of placements is an activity, that every student has to undergo. But anxiety should spur you into doing better and not bogging you down.
Packages are strictly a function of demand & supply. Also, your academics. Employers surely will like to get best value for their money. Hence top packages are offered only to 1 or 2 students.
Presently, IT rules the roost & if you are in top five of your batch you can expect 6-10 L. Others would get about 3-5 L.

Dear Kamlesh,In Indian education system, there is not any 'dual specialisation' exist. However, you can do double B.Sc in astronomy (from one institution in regular mode) and B.Sc in quantum physics from another college in distance learning mode. Actually, this is practically impossible but this is the only option you are left with if you are really want to do both at a single time. But my suggestion is that go for only one in which you are more interested.
Kindly upvote the answer if you feel satisfied.
Good wishes.
