Hello Yellakari Poojitha,

Firstly congrats for your GPA and percentile.You have good chances of getting into SASTRA.The admission there is usually based on both the JEE main percentile and 12th board marks.The weightage given to JEE main percentile is 25% and the remaining 75% will be given to your 12th marks.The SASTRA rank will be calculated based on these parameters and you will be called for counselling in the order of your merit.For you your GPA will be considered instead of percentage.You may fill your GPA in the online application form by choosing GP system and enter your various subject grades and GPA.
