The university - GRD Group of Colleges - has no mention of course fees for B.Sc. in Forensic Science on its official website. However, going by the general expectation based on similar careers being pursued at the institution, the usual fees payable for undergraduate courses in GRD Group of Colleges were expected to be between INR 50,000 to 70,000 per academic year.

To get the exact cost of fees, it is better to visit CGDC in person. The B.Sc. in Forensic Science at GRD Group will also equip students with theoretical and practical knowledge for crime scene investigation and laboratory work.

 The course lays the groundwork for various opportunities for students in national and foreign governmental agencies and laboratories.

Definitely, you can apply for admission in B.Sc even without passing mathematics in Class XII boards, if the university or college into which you are applying has such eligibility criteria. Most universities and institutes have a system to consider even overall marks, including the other sixth subject, for judging the eligibility. You will be declared as passed in board exams as it is assumed that you pass physical education as the sixth.

Specific B.Sc courses, mainly in mathematics, physics, or engineerings, may require qualifications based on eligibility which attach importance to mathematics. All universities would not have a flexible norm as such upfront, and many may actually require a pass in mathematics as core before admitting you to do B.Sc.

The eligibility requirement for every institution is different for B.Sc study. But, in case you are looking for courses like B.Sc. in physical sciences, biological sciences, and others, among which mathematics is probably not one of the compulsory subjects, then your chances of getting admitted in such a course will be relatively high.
