Hello aspirant

Percentile is not required for Sastra 

It take admission based on two factors 

• It is based on 12 th marks and jee mains marks. It takes 75% intermediate marks + 25% jee mains marks. Total marks is 165.The marks you get out of 165 is taken into consideration for admission. You need to score good marks in both IPE and JEE MAINS
• It will take admission only through intermediate marks but there are only 30%seats available, so for this you should have above 95+ because the competition is high

Hope this helps 

Good luck
