Hello T likhitha

WIth reference to your query ,I would like to inform you that admission in sastra are done on the marks scored in 12th which should be around atleast 90 percent and in mains 100+. They prepare their own meritlist on the basis of 2 criterias:One  scenario has 70% of seats. Admissions r given by taking 25% weightage of JEE mains and 75% of boards.Other scenario  includes admission on the basis of boards marks only. But it has only 30% of seats , so the cut off is high

Hope you found this answer helpful. Good luck for your future
