DMLT is the option as you will save you a year compared to BMLT. But I would suggest you to go for Masters as biotech is an emerging field and you have bright options as a biotechnologist. Also, if you are inclined towards medical labs, many genetic and molecular labs prefer biotech candidates.

Graduation with Chemistry has a lot of scope. You can work as a chemical analyst in chemical, fertilizer, pharma, food processing, dyeing and many industries. Also, you can apply for competitive exams or you can go for Masters for better job prospects.

IEM is rather accredited by NAAC. It has been given grade A.
