It is mediate, actually because if you get a seat through CET (Govt conducts exam for Karnataka Students) it will be around for 2 Lakhs for 4 Years while in COMED-K it will cost around 6 Lakhs while if you go through management seat, it will be around 10–20 Lakhs. So i hope this helps you to compare.
But COMED-K is worth if you get into top colleges.
