Science

Compartment is compulsory for improvement in maths.

IELTS or an English language test is necessary to study abroad.

There is a wide scope.
Microbiologists study microorganisms (microbes) in order to understand how they affect our lives and how we can exploit them. They focus on the biology of microorganisms at both the molecular and cellular level, as well as their ecology, including viruses, bacteria, archaea, fungi, algae and protozoa.
Their work can be relevant in a variety of settings including:
hospitals
agriculture
pharmaceuticals
biotechnology
environment.

According to me, B.Sc in computer science is a good option as compared to others.

The chances of getting a job abroad after B.Tech in food technology are also high. Many companies and industries placed in foreign countries like German, France, Italy, US etc recruit graduates in this field. The chance of getting a job will be more for post graduates. The salary scale will be in the range of Rs.60, 000/- to Rs. 1,00,000/- per month in the initial stage itself. With experience, they can even earn up to Rs. 2.5 Lacs per month.

MCA is a good option.
