Hello Kaushik,

There is nothing like minimum marks in JEE for admission in Sastra under stream 1.

Admission under steam 1- Applicants will be admitted to 70% of the seat on basis on JEE main score and normalizad +2 marks.

The combine score of all the students will be used to determine the sastra rank and the admission will be based on sastra rank secured.

Hope this helps.

Good Luck.
