B.Sc

In a broad sense, three options are available:
Option 1)
Let's say, you still want to stay in Biotech area: In that case, I would highly recommend going for M.Sc. or Ph.D. Now within this area, you may want to work in academia or industry. Based on your preference/goal, you can pick internships strategically and then get to where you want. Option 2)
Say, you want to do an MBA: You could do it abroad or India. In India, if you do your MBA from good business schools such as IIM/ISBs etc. , then your future is bright. But before that, get at least 2 years relevant work experience, even if it means low pay. It could be in a clinical lab, biotech manufacturing facility, or pharma side, or get into SALES/Marketing area. This relevant experience would make your MBA application standout from the rest and will help you get into a top-tier business programme. With such credentials, many top companies and consulting firms will want to hire you. Option 3)
Say, you want to still be in a related field but not move to a completely different field such as IT/ITES/BPO. In that case, multiple options are available such as getting a law degree (you can also do part time while you work in a law firm), going for an online course on Data Analytics/Science (you can get into market research, big data, clinical data analysis etc. ), or you could still pursue degrees such as homeopathy, psychology, Ayurveda etc. There are a lot of options, but many fail to see it or get to know about options in front of them. I hope, I addressed your question.
