Hi Karthik.

Hope you are doing good.

According to the fee structure the they can be put in this way in ascending order

1. KCET

2. COMEDK

3. Management

So, KCET conducted by KEA accepts less fees that is around Rs.60 to 65 Thousand per year.

COMEDK takes more fees than KCET and it is around 2-3 Lakhs per year.

You can go through this link:

And the management fees is more when compared to KCET and COMEDK. And it depends solely on the college itself.

And you have to pay the donation in the College Accounts section itself. For KCET you have to pay to KEA through the Banks.

Hope this was helpful.

All the BEST!!!
