Hello Avinash.

CUSAT is a very reputed university. Getting admission over there is not only difficult, but is also a tedious process. There is cut-throat competition amongst students to get a seat in the School of Engineering (SOE), Cochin.

With this score, I don't think that you will get in the first list itself. But towards the end, you might surely end up with a seat in the branch you want. Try to call them and ask them about the seats when the process is over. There will always be some seats left. You can surely apply for the institutional round.

All the best!
