Hello Nishant,
M.Sc in biotechnology has a good scope as the job opportunities for B.Sc graduates in a highly research oriented field as biotechnology is very less and most students tend to pursue M.Sc in biotechnology or a specialized discipline of biotechnology. India is a home to some excellent colleges for M.Sc programs such as JNU, DU, IISC, TIFR, IITs, etc.

Hello Deepraj,
You cannot do B.Tech and B.Sc together but you can do B.Tech and M.Sc together.
It is called a dual degree program. You will be awarded two degrees at the end of your undergraduate course.
For example,
If you have opted for B.Tech chemical engineering then you can do M.sc chemistry together.
Only some universities offer this dual degree program.
Hope this helps you.

Hi,
MBA programs abroad are mainly for experienced professionals. Around 2 to 3 years of work experience is required. If you have very good academic grades and a strong all-rounded profile, business schools may consider you. So focus on your studies, take part in extracurriculars, project works, exchange programs, etc. Take GMAT and TOEFL or IELTS too.
