You can directly secure a seat through SRM under management quota. You can contact the official SRM phone number which is available on their website and inquire about management quota. They shall furnish the required details and ask you to visit SRM vadapalani where the management quota admissions happen. If you are in Chennai you can directly visit any of the SRM campuses and ask the admission office regarding the same. They will direct you and guide you completely.
Hope this helps.
