Biotechnology

First see your priority like if you want to enjoy city life then go to Bangalore and if you want to experience college life and you surely want to learn something come to SRM Chennai. The reasons are as follows
1) just because it does not offer you better placement it will help you to expand as an true engineer it gives you immense amount of opportunity within the campus only.
2) BMSCE may be among the top ten colleges of Karnataka but SRM is among top 5 colleges in India. So choice is yours?
3) SRM gives you the opportunity to go abroad it has tie ups with top notch universities of the world like MIT carnege Mellon and lot more which I am sure BMSCE can't afford that much.
4) SRM has a very happening campus their timings are also not very tiresome you get many classes off in a day.
5) It has huge number of clubs like camber racing (manufacturer of f1 cars). SRM SAT they make satellite. Camber racing has won 2nd prize Asia for their design and marketing strategy.
6) Lot of prominent personalities use to visit our campus on regular basis. The most recent was the business tycoon Ratan Tata and CEO of hero motto corp and many more.I think this much is enough to understand the difference between SRM and BMSCE.

Biotechnology field combines biology and technology. It utilizes living organisms such as cells and bacteria in the industrial process. The best option open for you after obtaining a degree in biotechnology is research. The R& D departments of many government and private industries in the fields of agriculture, animal husbandry, health care, nutrition, pharmaceuticals, cosmetics, marine biotechnology, environmental conservation and waste management etc. Hire candidates with degrees in biotechnology. The scope of biotechnology in India is good, but mostly in the research and development field. If research is not your calling, then you can also apply for many other positions such as sales and marketing, quality control, administration, laboratory assistants and field technician. There are also many disciplines related to biotechnology that you have the option of getting into, should you choose to. These include genetics, microbiology, biochemistry, immunology etc.

Yes. You can acquire as many degrees as you would want to, but then you should possess minimum qualifying percentage for the course of study. MBA colleges in India are either accepting admissions through entrance exams or without any entrance exams.
