Hy dear!!

Opting forensic science after your 12th is a good choice for your career. The percentage required for pursuing forensic science might vary from college to college.  The eligibility for forensic science is that you must have had either PCB for PCM in your 12th standard and must have got an aggregate of of at least 55% marks in your 12th board. Some universities might conduct their own entrance exams for the admission in forensic science.

hope it helps you !!

all the best!!
