Hello dear aspirant

The cutoff trends changes every year and it depends on the number of students appearing in the examination, difficulty level, number of available seats, etc. Getting a CSE seat is becoming really hard these days because of the huge demand.

According to your mentioned marks and previous year trends, your rank might be in the range : 10,00-13,500 (this may or may not be accurate due to varying trends every year). For open state quota previous (2017) closing rank for CSE was 1813. So there aren't much chances according to this. You can try applying for CSE in their Amritapuri campus. With this rank, you can almost get any branch in any of the other campuses like Bangalore, Amritapuri, etc but not Coimbatore. Just apply to their counseling process and know the exact cutoff.
