Hello aspirant,

Hope you are doing absolutely great.

So with regard to your query, YES your seat will get automatically cancelled in case if you don't join the allotted college in the counselling round of KCET. However, this does not mean that you cannot cancel the seat. You can also cancel the seat by yourself.

Hpe this helps you,

Good luck, Thank you.
