Hello Hima. SASTRA university does not give admission only on the basis of JEE mains, it also considers the board percent which should be 95+ or minimum 90+

And in mains 100+. They prepare their own meritlist on the basis of 2 criterias:

1. First criteria has 70% of seats. Admissions r given by taking 25% weightage of JEE mains and 75% of boards.
2. Second criteria includes admission on the basis of boards marks only. But it has only 30% of seats , so for this criteria u should be having 95 or 95+ for securing ur seat as in this criteria competition may be very tough.
