Hi Vipin,
Bachelor's in Forensic Science is a really good and upcoming course in India. A lot of students now are opting for this course. Kerala has some good institutes like
1. D.B College
2. Devaswom College
3. Christ College
4. C.M.S College
5. Indira Gandhi College of Arts and Science
These are some really good institutes which are also approved by the government and are well established and reputed.
Good Luck
