Hi, The marks that you calculated may or may not be right. It is only fair for you to take a specific range. My best guess for your range would be 30 to 40 marks. Given the situation the minimum marks for a student from general category and OBC is 30 whereas, there is no minimum qualification for SC and ST. Getting into a government college is likely not possible. Looking at the bright side, I believe that you can apply for Private Colleges.
