By my predictions I can Opt 80/165.Can I get into CSE Branch

that's low I know can I get

Ajay Patil Ajay, you see..
Admissions are provided to B.Tech./ 5-year Integrated M. Tech. programme under two streams. You are eligible to apply under both streams.
For stream 1 (70% of the seats), your admission will be based on Class 12th aggregate percentage and marks obtained in JEE mains. The formula I have mentioned above will be used and based on your marks out of 165, you will be given a SASTRA rank, depending on which you will be provided a seat.
So, if you think that you will get 80/165, then chances for getting CSE branch are not much high for you.
Getting 100+ out of 165 assures a 9/10 probability that you'll get a seat here.

But yes, you have got one more alternative. Coming to stream 2, you can apply for it and sit in the counseling process for the rest of 30% seats. Your normalized 10+2 level aggregate percentage is only considered here.
So, if the highest scorer has 97% aggregate in boards and you have 90% aggregate, your normalized % will be (90/97 x 100) = 92.78 %
If there's a vacancy in Stream 2, you may get a seat in the branch of your choice. So, you should attend the counselling for stream 2 even if you get admitted under Stream 1 to any other branch of lesser interest. That means you should apply for both streams.
