Hello aspirant.

In Shanmugha Arts, Science, Technology and Research Academy (SASTRA) university For BTech admissions, 70% of the total seats are filled on the basis of the JEE Main rank and rest 30% based on class 12 merit .

The admission is based on two ways 1: JEE main marks + board exam marks (70% seats) 2: only board exam marks (30% seats)There is no specific cut off to get a seat in SASTRA University. It depends on the student who scores the highest marks. If you have appeared for JEE Mains then apply under  1. If your board exam marks is 90-95% and JEE main marks is between 50-120 then you can get admission under  1. For  2, your board exam marks should be at least above 85-90% to get a seat and if it is more than 95% you can get a good course.  Moreover, you have to score minimum 90+ percentile in JEE Mains to get a seat in SASTRA university.

Hope this will help you.
