Dear Jerin

You can look at previous years' cutoffs to check the availability of seats in your desired branch, i.e Computer Science, according to your rank.

You can refer to the following link- https://engineering.careers360.com/articles/keam-cutoff

Accordingly, you can get the following colleges-

S C T College of Engineering, Pappanamcode
University College of Engineering, Kariavattom
College of Engineering, Perumon
College of Engineering, Chengannur, Alappuzha
College of Engineering, Adoor
Govt. Engineering College, Mananthavady
Govt. Engineering College, Sreekrishnapuram

Thus, it is apparent that you are getting decent number of options. Select further on the basis of your priorities like location, etc.

I hope this helps. Feel free to ask any other queries.

All the best!!
