Hello Chandu,
SASTRA University does not give admission on the basis of JEE Mains only. It also consider the board percent which should be 95 % and above or minimum 90 % and above.
And in Mains, 100 and above marks is required. They prepare their own merit list on the basis of 2 criteria:
First criteria has 70% of seats. Admissions are given by taking 25% weightage of JEE Mains and 75% of boards. Second criteria includes admission on the basis of board's marks only. But, it has only 30% of seats. So, for this criteria you should be having 95 or 95 and for securing your seat, as in this criteria, competition may be very tough. I hope this will help you. Thank you.
