Science Scope

Nano science deals with the nano size particles, which have size of less than or equal 1nm. It includes research in field of electronics circuit or biology, in which you will study about very minor particles. In biology, nano science deals with organisms, which are very small in size.
In electronics engineering, it deals with nano size devices or circuits like transistors and ICs. You can pursue B.Sc or B.Tech in nanotechnology or B.Sc in microbiology. The scope for this field is good in India. As per technological development, it will have great future in India as well as in other countries.

Hello Sagar,
You can go for B.Sc in physics, chemistry, mathematics or computer science.
You can also consider below mentioned options:
1. BCA.
2. B.Sc IT.
3. B.Com.
4. BBA.
5. B.Arch.

This course is not having much scope in India but is having a huge scope in foreign countries as you can get an awesome salary with a lot of perks in this field abroad.

Forensic science is a niche filed with very limited career growth opportunities in India. The majority of forensic science graduates are connected with police departments or research centers. You are advised to take this as a professional career, if you are really interested in making career as a forensic scientist.

They have a vast scope. If you want to pursue robotics , then take admission in a good Institute that really teaches you about the technology used in today's world and provides you with practical exposure.

If you want to make a career in the science field, and if you have a dream of pursuing post-graduation from IIT's or IISC, then you can prepare for IIT entrance exams.
You can pursue M. Sc./Ph.D. & other post-graduate courses by clearing IIT-JAM entrance test.

Nobody can guarantee but you will have a good chance if you passout with very good grades, a few years of work experience or interning and research work in Germany will be helpful.

I will suggest you to pursue B.Sc. in CS and after that you can do Masters in the same as there are great opportunities for you.
All the best.
