B.Sc

Abhinash, Science has often been termed as the stream of opportunities that offers immense prospects of employment and further education in a variety of fields including those dominated by the humanities students.
Science is an internationally accepted applied discipline that deals with the study of nature and the universe as a whole. Scientists study nature and universe as well as all the laws that govern both of these entities making it a universally intriguing subject. The main goal of a B.Sc degree in any subject is to develop a deeper understanding of natural laws, inquiring about the reasons and logics which govern them through established methods of observation, modelling, experimentation and calculations. This makes B.Sc degree a very important weapon in your arsenal and opens a plethora of opportunities for further studies, research as well as lucrative employment opportunities across the globe.
Students can opt for B.Sc in core Science subjects like Physics, Chemistry, Botany, Zoology, Maths, etc or can also opt to join an applied Science subject to pursue their graduation degree in Science like Computer Science, Microbiology, Animation, Multimedia, IT, Biotechnology, Bioinformatics, etc. The employment opportunities available to them are not only great in terms of pay package and perks but also a satisfying job experience. They can be hired by a number of different organizations involved in scientific operations at entry level and mid level positions.
B.Sc graduates can look for lucrative employment opportunities in the following sectors depending upon their interest and specialization subject:Health Care Providers

Vinit, Microbiology is the study of microorganisms, which are unicellular or cell-cluster microscopic organisms. In short; microbiology refers to the study of life and organisms that are too small to be seen with the naked eye. It is a broad term which includes virology, mycology, parasitology, bacteriology and other branches.
Biotechnology is technology based on biology, especially when used in agriculture, food Science, and medicine. It combines disciplines like genetics, molecular biology, biochemistry, embryology and cell biology, which are in turn linked to practical disciplines like chemical engineering, information technology, and biorobotics. Patho-biotechnology describes the exploitation of pathogens or pathogen derived compounds for beneficial effect.
If you are interested in research work than Microbiology will be the best for you. Otherwise both the branches are equally good.
Now institution plays an import role. There are many good universities that are offering these courses along with good placements.
Check some websites for more details.
Good luck.
