hi,

see forensic science works related with crime control branches, social security and legal acts, generally bsc in forensic science is 3 years duration, after completing bachelors you may work as a lab assistant in different centralized labs in forensic departments of india, one major draw back is there is not much hiring comes for forensic experts, but of you go for masters or phd course there is lot of subjects available for research options, you also can work in abroad in relevant discipline.
