Hi, so basically sastra requires no minimum percentile no Cutoff.

It is based on 12th percentage and jee main mark(sastra will calculate like this 12th percentage * 0.75+jee main mark * 0.25)

Total 165 marks.

And Out of 165 marks what is your marks based on that they will give the seat.

Therefore there is no minimum percentile you need.

However you need to score good marks in both (12th AND JEE MAINS).

Hope this is helpful
