Hello dear student,

As you said you belong from Kerala and you want to do BSc Hons physics from Delhi University. show the steps that you need to follow a very simple you just have to go to the Delhi university website it after the CBSE will published the results of class 12 for this year. You just need to fill the application form to get admission in Delhi University. Then after this procedure is finished they publish cutoff regarding different courses with respect to different categories of different colleges. You need to keep a check on the cutoff that will be released by the University. Hence where your marks will be lying you can take admission in that college.There is one point that I would like to add you class 11 marks does not make you eligible to take admission in Delhi University you need to have a good range of marks in class 12 because on the basis of class 12th marks only you will get admission in Delhi University.

I hope this was clear and helpful

Thank you
