Biotechnology

Bio-engineering is the application of principles of biology and the tools of engineering to create usable, tangible, economically viable products. Following are subjects of Bio-engineering:
Mathematics
Physics Chemistry
Communicative English
Environmental Science
Engineering Thermodynamics
Computer Programming
Electric circuit analysis
Electron devices and circuits
Switching theory and logical design
C+ and Data Structures
Human Anatomy & Physiology
Dynamics of Bio-fluids
And many more subjects in this Field. Biotechnology is the use of living systems and organisms to develop or make useful products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use".

Well, B.Sc Biotechnology is also one amongst the traditional courses, but yes it is definitely a good course. However, when you measure the same with Law it definitely is beyond comparison, as both have different implications on career. However, Law as a course has gained much popularity in the past years, but one should remember that Law needs an interest in a student without which, you won't be able to survive your law school. Also, it is important to follow what interests you more. Only then can you see your career as a settled, and you will be able to make your own ways. Both the options are good, and remember not every student gets a placements at an institute. You need to be really good at what you pursue.
