SASTRA (Deemed to be University)

You can apply for stream 2 which is totally based on +2 marks. There is less competition for bio informatics in stream 2 sector.

The rank is totally based on how many students applied and the highest score in that year. According to 2018 rank, you will stand between rank 1000-1500 and in 2019 as Andhra Pradesh government.

Grade points became a major missing of AP students in campus . They considered only 920 marks out of 1000 when they got 10 points because as they don't the actual marks of students . It made a very less oppurtunity for Ap students who scored very good jee score of 95 percentile with 10 points to join in very less dept. So it's tough to get ECE with your score as per the last year scenario .
Maybe if you join in any branch now and if you score 9 above GPA in first year of btech you can get your ECE seat .

You have to apply through both of the admission streams as described below in SASTRA.
Stream-1 (JEE Main+!2th Marks) : 70% of seats will be filled through this stream. 25% and 75% of weightage are given to JEE Main and 12th marks respectively.
Stream-2 (12th marks based) : 30% of seats will be filled through this stream and 100% of weightage is given to 12th marks. So you have good chances of admission through stream-2.
