hello. You won't be able to get B.sc Physics in any of the DU colleges with your reported 12th marks. I checked the DU 2018 10th cutoffs and the colleges accepting SC students were having a minimum of 68-70% of marks. But you might get B.sc physical science with chemistry in Acharya Narayan dev college which had 10th cutoff % of 58% in 2018.
here is the link to DU 2018 10th cutoff: http://www.du.ac.in/du/uploads/Admissions/Cut-off/2018/10th%20Cut-Off%20-%20Science.pdf
You can check for other Courses too if you would like to rethink your choice of course.
