Hi Tanmoyee,

There are a large number of options. First you need to realise your interest towards a particular subject. If you like more than one subject then also you can choose a amalgamated subject.

A large number of vocational courses are available to study.

Ranging from biotechnology to biochemistry to industrial microbiology to forensics to basic sciences.

A large number of options are there.

You just need to explore your interest and work accordingly.

I hope this information helps.

All the best.
