Psychology

Forensic science is basically using the principles of science to solve and analyze criminal cases, whereas psychology is mostly the study of the human mind and tries to determine the psychological factors which lead to the crime. Both of them deal with the legal system but employ different methods in their application.

Dear Reshma,
If you aren't any more interested in psychology then you can go for PG into some other subject of your choice. However, psychology is a very interesting subject and it not a cup of tea for everyone. If you study ahead and work hard you will definitely get success. I hope this would suffice. All the best and god bless you.
