Hello Pranav Raj,
If you wanna get admission in Govt. Quota it’s better to write COMEDK or Karntaka CET.
As per I know if you want to get admission in ECE, CS and EEE your ranking must be below 2K(For KCET don’t know about COMEDK). And as per Karntaka rules for UG admission your score must be minimum of 50–55% in PU or 12th class.
And you can get management quota also, but college fee depends on College administration.
