Hello Akshay,

Congrats for your GPA and percentile.There are chances for you to get CSE/ECE SASTRA.In SASTRA the admission is based on both JEE main percentile and 12th board marks.The weightage given to JEE main is 25% and the remaining 75% will be given to your 12th marks.If there is a tie in the marks between students then your physics, Chemistry and Maths grade points will be considered and based on that the order of merit will be decided.The SASTRA rank will be calculated((JEE main percentile*0.25)+(12th percentage *0.75)) and based on that you will be called for counselling.For you your GPA will be considered.You can apply either through online/offine mode.
