hello aspirant,

Actually Government colleges are not decided or allotted to students based on the marks scored by him/her in KEAM exam. It is the KEAM rank which decides which  government or aided colleges will a student gets based on the KEAM rank. As per previous year KEAM cutoff trends, in order to get CSE in government Colleges you will have to score a rank of 8K or less (to be on the safer side).

Further, to know more about the KEAM cutoff for previous yera for CSE, you can follow the below mentioned link to know more : https://engineering.careers360.com/articles/keam-cutoff

I hope that this will help.
