Hello Putchakayala,

First of all congrats for all your GPA and percentile.In SASTRA University , the admission is based on JEE main percentile as well as 12th marks scored.The weightage of JEE mains is 25% and remaining 75% will be given for 12th marks.The SASTRA rank is cacluated based on these parameters((JEE main percentile*0.25)+(12th percentage*0.75)).Based on this rank, the students are called for counselling based on merit.Since you have a good GPA and excellent percentile you have a very high chance of getting your desired branch in this University.

Hope this was useful.

Wish you all success!!!
