Hello,

If you are not willing to join then you can reject it or upgrade it. You won't get penalized for that. You will pay penalty only when you have accepted the option and not willing to take admission.

if you have to accepted it then reject the college option which you got and apply for upgrade. if you don't get any college option by the end of counselling process then your counselling fee will get refunded.

Until and unless you don't accept the college option there will be no penalty. for more query, visit the help desk of the counselling body.

Hope it helps!
