Hello Aspirant,

In SASTRA for UG admission both JEE main percentile and 12th board marks will be considered.The weightage of JEE main is 25% and the remaining 75% will be given to aggregate marks obtained in 12th board exam.Based on a particular formula, ie (JEE main percentile*0.25)+(12th percentage*0.75) the SASTRA rank will be calculated and based on the order of merit you will be called for counselling.You have good chances there, since you have an excellent GPA.When you fill the online application form choose GP system and enter your subject grades and GPA instead of percentage.
