Hello aspirant

The admission in sastra university is based on two ways 

Stream 1: 70% seats are allocated by considering both( jee mains marks + board marks) 

Stream 2: 30% seats are allocated by considering only ipe marks. But it has tough competition

For getting an admission in sastra through stream 1  you need to secure 90-95% in ipe and 50-120 marks in jee mains i. e above 90% 

As you got good score in both you will get cse or  seat in sastra 

Hope this helps

Good luck
