Hello aspirant,

SSN has a merit based selection even for the management seats which is really rare to find these days. So students from Andhra Pradesh can fill up the management applications once you have got your class 12 results. I think forms will be issued for students having more than 85% marks. Once you submit your marks, you'll be called for the test and interview if you are shortlisted. The test consists of basic aptitude test and then there will be a personal interview. All the process will take place at the campus itself. The initial shortlisting will be based upon the cut off marks and for CBSE students 5 marks will be added to their current cut off. They will declare the list of selected candidates within a month's time.

Hope this helps,

All the Best!!
