Visit the page: https://hp.online-counselling.co.in/admissions/onboardingRegistrationInstruction and click on Yes to read the Instructions and then the Prospectus will be downloaded. You can also go through the prospectus at: file:///C:/Users/dell/Downloads/HP_MBBS_PROSPECTUS_2020.pdf. The prospectus doesn't give you an option to avail both OBC and single girl child reservations. The application form allows you to select only one Category for availing reservation. So you have to choose between OBC and Single girl child reservation.
