Hello Siva,

SASTRA deemed university will invite admissions to B.Tech program through stream 1 in which JEE Mains paper 1 and 10+2 marks will  be considered and through stream 2 in which only 10+2 marks will be considered for admission. 

As for your question, the fee will be fixed unless you are from a economically weaker section in which case you will get scholarship from the government.
