B.Sc

If you are a BSc student in biotechnology or any other biological sciences related fields, it is highly recommended that you pursue your MSc. The job opportunities for BSc graduates in a highly research oriented field as biotechnology is very less and most students tend to pursue their MSc in Biotechnology or a specialized discipline of biotechnology. India is home to some excellent MSc programs such as JNU, DU, IISc, TIFR, IITs etc. With an MSc degree, most students tend to work in research labs and industries as research assistants. The pay package is also quite less for MSc graduates. Since India is still developing, it is highly recommended that you do your MSc in a reputed institution for good campus placements and job opportunities. If your university is not reputed, chances of any biotech company coming for placements will be zero.
