Hello Vishal,

From the official website of SASTRA check for the application and fill it up.

Submit your filled application with the enclosures u have to submit through the post for SASTRA University Address.

After your submission, your grade sheets and certificates are verified by the staff based on your marks and based on the stream through which you have applied they will announce the All India Rank based on the Streams or Ranks they will call you for counseling if u have got decent AIR.

You have to attend the counselling and take the seat what you get for your marks.

If you want to get seat in SASTRA then you should have good board marks or you should have good JEE mains (>100). Then you will definitely get seat in SASTRA.

Hope this helps.
