SASTRA Engineering College is a prominent deemed university known for its world class quality in academics  and research. SASTRA allocates seats based on 2 criteria, namely Stream 1 which holds 70% of seats and Stream 2 which holds the rest 30%.

Stream 1:

The weightage for +2 marks and JEE Mains score will be 75% and 25% respectively. The aggregate JEE Mains score and the normalized +2 Score will be taken into account. The normalization process is primarily based on the topper's score. But it may vary accordingly. The amalgamated score of all students will determine SASTRA Rank and the admission will be based on this rank criterion. There is a good chance to  get in if your SASTRA rank is up to 4000.

Stream 2:

30% of seats of each branch are filled through Stream 2. But hoping for this is uncertain.

Since, you have good score in your boards in addition to JEE Mains, you can definitely try at SASTRA. You have adequate chance to get threw in.So, have your precision towards the stream you desire.You'll definitely receive, one of the streams which you've explicitly mentioned above.

Good Luck!
