As far as the scope of the course is concerned then the field of Biotechnology and Forensic Science is very diverse field and has lot of potential in future.
In india at present it lacks opportunities because government doesn't isn't giving much attention to sectors related to this field but in future there will definitely be log options and especially in research.So, if you are interested in this course then i would say you must go for it.

I hope this helps.
