hi krishna,

the admission in sastra is based on two ways one is jee mains rank+board exam marks (70% seats) , you donot have chance in this category since you have mentioned that you have not qulified in mains. the second is based only on the board marks (30% seats) . there is no specific cutoff for this category .it depends on the student who scores the highest marks.

so, you have pretty good chances to get a seat in sastra university.

hope the information was helpfull

all the best:)
