Dear Aspirant,

The admission in this college is based on two ways:
Stream 1: JEE main marks + board exam marks (70% seats)
Stream 2: only board exam marks (30% seats)

For admission in SASTRA University through stream 1, 25% of JEE Main and 75% of 12th standard marks are taken into view. And on the basis of them every candidate is given a rank. The admissions are on the basis of these ranks.

Also by looking at your academics its possible you can get admission in Sastra but again it depends upon the course in which you want to enroll.

Hope this Helps!

Good Luck
